PICTURED: Glamorous Megyn Kelly arriving at The Late Show hand-in-hand with her husband and hot off back of $10m book deal 

Megyn Kelly has gone from TV host to guest as she and her husband, novelist Douglas Brunt, arrived hand in hand to The Late Show with Stephen Colbert.

Kelly, 45, was all smiles in the same elegant black jumpsuit she later wore on air. Brunt, 44, opted for a casual pair of jeans and dressed it up with a blazer.

The Fox News anchor was just about to reveal how she would welcome back Donald Trump during  the network's next GOP debate on March 3.

She wouldn't say what her first question would be, but instead joked that her first comment would be: 'Apology accepted.'

Kelly, 45, and Brunt, 44, have been married for eight years and have three children together. He couldn't wait to find the perfect ring to propose so he bought one in a costume shop as it reminded him of the blue diamond featured in Titanic

Kelly and Brunt got married in March 2008 six months after he proposed in Beach Haven, New Jersey, the New York Times reported at the time.

Brunt couldn't wait to find the perfect ring and instead bought one at a costume store because it reminded him of the blue diamond featured in Titanic.

They had broken up once before the wedding after Brunt let one of Kelly's dog escape during a walk, according to the newspaper. The Shih Tzu was almost hit by a car and Kelly accused him of trying to kill her pet.

They made up shortly afterwards and tied the knot at Oheka Castle in Huntington, New York. Kelly was wearing a Joanna Mastroianni gown.

Kelly and Brunt have two sons, Yates and Thatcher, and a daughter, Yardley.

The two went out last week after Kelly reportedly struck a $10 million book deal.

It will be released in the fall by HarperCollins, Deadline reported.

Speaking on the Stephen Colbert show on Sunday night, the FNC show host revealed that she knows exactly what she's going to ask Trump in her opening question - but stopped short of saying what it was

But Kelly told Colbert that she doesn't regret questioning Trump on his history of making derogatory statements about women

Speaking to Stephen Colbert, Kelly - who celebrated signing a $10 million book deal just days ago - dished the dirt about her long-running feud with Trump and admitted that she didn't like that she had become the center of the story.

Their 'beef began' when Trump lashed out at Kelly in the press after the first GOP debate in August, accusing her of singling him out and then refused to take part in the most recent Fox debate ahead of the Iowa caucuses.

But Kelly told Colbert that she doesn't regret questioning Trump on his history of making derogatory statements about women.

She said: 'I asked him a debate question he didn't like, I still think it was a very fair question.'

Kelly said that she was 'not feuding' with him, but felt that he had 'beef' with her.

Kelly tweeted a photo of herself looking camera-ready before her appearance on The Late Show with Stephen Colbert on Sunday night

The host even went as fair as to say that she 'looking forward to having him on the panel'.

Talking about what she would ask the presidential hopeful - who Colbert described as 'just a billionaire who wants to have the nuclear launch codes' - she joked: 'I'm gonna start with, 'Apology accepted.''

Before adding, 'I'm looking forward to him coming. All the questions I had for him the last go-round, I'm just gonna move over to the March 3 debate rundown. 

Trump has been extremely vocal about his feud with Kelly and tweeted this comment back in January

The 'beef' between Trump and Kelly began in the press after the first GOP debate in August, when he accused her of singling him out and then refused to take part in the most recent Fox debate ahead of the Iowa caucuses

'We're gonna have at it, just like I've had at it with all the other guys — and Carly — who've been up there. It's gonna be a robust exchange and I think he's gonna walk away saying, 'What was my problem?''

She concluded, 'It's gonna be fine between us.'

When pushed to reveal the question she has prepared for him she responded: 'The only thing I really wanted to ask him was — he recently said that his supporters are so devoted to him that he could go in the middle of Fifth Avenue and shoot somebody and he wouldn't lose a single voter. In response, I want to ask him, 'Were you talking about me?'' 

Stephen Colbert playfully taunted Trump, inviting him to switch on his television to watch Megyn Kelly on air in case he felt the need to vent

President Obama made a guest appearance in a pre-recorded tape. When asked if he watched the game he said: Of course, I did

After fielding questions about what happened in the game, Obama insisted to Colbert that their interview (during Colbert's live after-show) was pre-taped and so to prove that it was he tossed a ball to Michelle who was in the next room 

She joked that she doesn't visit Fifth Avenue anymore and called the feud a 'surreal experience'. 

Conversation then turned to how she feels about being labeled a feminist icon, but Kelly says she rejects the terminology. 

She said: 'I think word feminist is alienating and has been co-opted by some people'

And added that her advice would be to follow Steve Martin's motto: 'Be so good they can't ignore you', saying that the best way forward for young girls would be 'work your tail off, be the best, make sure you can't be ignored'.

After her appearance on the show a viewer tweeted saying: 'Respect Megyn Kelly 4 working hard. But what about the women who aren't professor's daughter & have law degree. What about average women?'

To which she replied: 'My dad died when I was 15. I put myself thru law school w/loans. My mom was a nurse. Anyone can pull themselves up.'

Her tweet has since had more than 700 retweets and has been liked more than 2,000 times.

After Kelly's appearance on Stephen Colbert's show, a viewer addressed her on Twitter, praising her hard work but wondering how other women could achieve the same success

Also on the show was Tina Fey and Margot Robbie, who were there promoting their upcoming film, Whiskey Tango Foxtrot.

Next was Will Ferrel who managed to dodge any questions relating to his upcoming film, Zoolander.

And President Obama made a guest appearance in a pre-recorded tape.

When asked if he watched the game he said: 'Of course, I did. After every super bowl I call the winning team and congratulate them, and sometimes I also call the losing team, because sometimes I bet on them.'

He said he knew the Denver Broncos won the game, because 'all of the Super Bowl winners are written on the back of the constitution.'

After fielding questions about what happened in the game, Obama insisted to Colbert that their interview (during Colbert's live after-show) was pre-taped.

To prove it, Obama walked an earlier Colbert onto the screen.

The president, who earlier did then threw the football over to the First Lady, who was in the next room leading a touchdown dance with a group of children.
