'My rhymes are Pitch Perfect': Rebel Wilson beats David Schwimmer and James Corden in another rap battle on The Late Late Show

David Schwimmer and James Corden went head to head in a late night rap battle on Wednesday only for both to be beaten by actress Rebel Wilson.

The former Friends star appeared on The Late Late Show with Corden and mocked the host for being 'destroyed' earlier in the week by Anne Hathaway during a segment of Drop The Mic.

Corden told Schwimmer there was no way he should be challenging a 'rap assassin' to a lyric battle.

'It will be a blood bath, I will destroy you,' bragged Corden.

'Let's go. I'm serious,' Schwimmer mugged for the cameras.

The actor then took to the stage wearing a Rocky-style boxing robe before the pair went to work in the show's second rap battle of the week.

Corden kicked off by teasing Schwimmer that no one actually remembered who he was.

'Millennial let me introduce you to this guy, his name is David he was famous back in '95,' rapped Corden.

'That's when he was hot, he was on TV then, now its 2016 and he has no friends, get it, no Friends, not famous ever again.

'He was a Kardashian on TV but that was only for pretend. You played Robert and that was a great combo but you were so white you should have probably played the Bronco.'

James finished his rap by poking fun at Schwimmer's relationship with former co-star and love-interest Jennifer Aniston on Friends.

'Now you have the chance to prove you've got balls while I ignore you like Jennifer Aniston does your calls,' teased James.

Schwimmer was up to the challenge and got up close and personal to rap right into Corden's face.

'A Brit in America is your one claim to fame, we all know as an actor your roles were all the same. The heavy best-friend, the humorous sidekick with a belly so big you can't find your own d***,' Schwimmer rapped.

'Dickens the author we all read as kids, he's British like you but people know who he is, you must be a masochist you want to battle me, this won't end well mate it's not Love Actually.

'To be clear I love the English, I married your kind, but why your wife chose you? My bad, she blind?

Good one: The Friends star ripped Corden's acting career

'Rap was born in this country you're a tourist here, do us a favor James, just change your career.'

Corden would not be kept down and was straight back on the attack, but Schwimmer smiled a few times before getting in his own final say.

'You're late-night, I'm prime-time, you're cola, I'm fine wine, go home, you're done, this battle is mine.

Prime time: Corden looked shocked as Schwimmer continued with his rap

'Did you think I'd be scared, walk around gingerly when everyone knows your middle name is Kimberley?'

The crowd roared with appreciation at the diss with James rubbing his face in disbelief.

'I'm tall and lean, you're short and stout, they know me in Japan, they know you at In-N-Out. You embarrassed your country, this was easy for me, bitch lay down the mic and go make me some tea.'

Schwimmer then flashed his middle finger and told Corden: 'One cream, one sugar.'

Right at the end Rebel walked onto the stage to get involved in the battle.

'Enough of this crapping why the hell do you want to hear two white men rapping?' she shouted.

'Im the Rebel MC, I'm crackalackin' I come packing boobs show these dudes what they're lacking.

Here she comes: Wilson was a late entry into the rap battle

'David, your career, it's a huge mistake, it's like Ross and Rachel, it's on a break.

'All jokes aside man I think you're great,' I'm your biggest fan when I was eight.'

She then turned her attention to Corden.

She's good: The Australian actress quickly shredded Schwimmer and Corden

'Carpool Karaoke, you think it's your big thing, but everyone is thinking ''Shut up and let Adele sing.''

'You speak English but you can't even rap, your rhymes are nonexistent like my inner thigh gap.

'Don't battle me because you know it's not worth it, everybody knows my rhymes are Pitch Perfect.'

That was enough to secure Wilson the win to roars of appreciation from the crowd.

Wilson later left Schwimmer and Corden red-faced with a suggestive gift from China.

The Australian actress presented the pair saucy ’I Love BJ’ T-shirts she picked up on her recent trip to Beijing.

‘I thought these would be perfect,’ she laughed as she handed them over to the guys.

‘These are everywhere in Beijing. I don’t know if they understand it?’

The T-shirts definitely seemed to amuse James.

‘I’ve got to be honest I agree with the sentiment, I do love BJ, I do,’ he said and Rebel agreed.

‘Yeah, Beijing is great,’ she said.

Schwimmer joked that he was going to take ‘a long, sweet time putting this on.’

‘You don’t want to put it on now?’ Rebel asked him cheekily.

‘No, not right now.’ he replied.

James said he would put it on later to ‘surprise’ his wife.

Good times: Corden and Wilson laughed as Schwimmer talked

‘I will get into bed and say ''Hey babe, guess what?'' as he put his hands behind his head suggestively.

Schwimmer later told Corden that he was thrilled with the success of The People Vs OJ Simpson.

‘It was really cool though to be part of a show that was a watercooler show. I would say hi to people on the street and they would say ''What happens next week?'' Everyone knows what happens but it was cool to be part of a show like that,' Schwimmer said.

Corden told David that Wilson in fact got a law degree before becoming an actress.

‘A lot of people think I’m like stupid, they do. They are like that Rebel Wilson, not much up there but plenty here,’ she said pointing at her breasts.
