'He was definitely serving two hams': Bette Midler pokes fun at Justin Bieber's naked photo... after feuding with Kim Kardashian over THAT nude selfie

She had a war of words with Kim Kardashian earlier this month after the reality star shared a now infamous nude selfie.

But Bette Midler isn't backing off, and has now poked fun at Justin Bieber for sharing a naked picture of himself.

The 70-year-old couldn't resist making a joke after she saw the 22-year-old showing off his bare bottom on Instagram over the weekend.

'His eggs were hidden': Bette Midler poked fun at the naked photo Justin Bieber shared over the weekend

'Justin Bieber Instagrammed a nude pic on Easter Sunday,' she tweeted on Monday. 'His eggs were hidden, but he was definitely serving two hams.'

This is not the first time that the pop star has been the 'butt' of Bette's jokes, and he famously said he had no idea who she was after naked paparazzi photos of him started circulating the internet in October.

Bette took issue that Justin's father Jeremy tweeted to his son, writing: '@justinbieber what do you feed that thing. #proud daddy.'

The actress then wrote: '@justinbieber dad tweeted he's proud of his son's penis size. I think the biggest d*** in this situation is the dad who abandoned his son.'

In an interview with Billboard, Justin then said: 'This Britt Meddler. I don't even know who that is, honestly. I wanted to immediately say "Who is this lady?", but then I'm just fueling this negativity.

'I do feel the photo was an invasion of my privacy. I felt super violated. My dad made light of it, but I don't think that’s sick and twisted. It was funny. Dads are going to be dads.'

Bette then hilariously tweeted the singer again to say: '@justinbieber Britt Meddler! I don't know who that is either! But damn that b****!'

Justin has yet to respond to the Beaches star's latest tweet.

While some people criticised Bette for 'slut-shaming' Kim Kardashian earlier this month, it's clear she will poke fun at any celebrity who goes naked on social media.

However the Hocus Pocus star probably wasn't expecting to get into a feud with the 35-year-old after joking about her nude selfie. 

'Kim Kardashian tweeted a nude selfie today. If Kim wants us to see a part of her we've never seen, she's gonna have to swallow the camera,' she wrote.

Bette wasn't the only person to weigh in, with Chloe Moretz and Piers Morgan slamming the star for her picture.

Kim then fired back at all three them in a Twitter rant, writing to the actress: 'hey @BetteMidler I know it's past your bedtime but if you're still up and reading this send nudes #justkidding.'

She added: 'hey @BetteMidler I really didn't want to bring up how you sent me a gift awhile back trying to be a fake friend then come at me #dejavu (sic).'

But Bette shot back with a withering zinger, tweeting the next morning: '@KimKardashian: I never tried to fake friend you. Looks like anyone can take a selfie but not everyone can take a joke...'

According to TMZ, the gift in question was a tree that Bette planted back in 2007 in Kim's honour, as part of her MillionTreesNYC restoration initiative. 

The actress apparently sent the reality star a handwritten note and dedicated one of the trees to her.

Kim also joked that she had paid off the $53m debt her husband Kanye West claimed to have, writing: 'Sorry I'm late to the party guys I was busy cashing my 80 million video game check & transferring 53 million into our joint account.'

The mother-of-two finished off her rant by sharing another naked picture, this time with the caption: 'Liberated.'

Some Twitter users wondered if the tweets had been sent out by Kim's husband or her outspoken sister Khloe, but she insisted that she was absolutely the person behind them.

'Wait I can't believe people thought Kanye or Khloe hacked my Twitter. I swear I'm funny too!!!' she wrote.

'Anyone can take a selfie but not everyone can take a joke': Bette responded with another withering singer

Speaking her mind: The Beaches star, seen here in September, is not afraid to tell it like it is
