Joe Swash jokingly walked off Good Morning Britain today after he was mocked over his short trousers.

The former EastEnders star, 37, was mocked by pal Ben Shephard live on the show after he noticed that his trousers only reached his ankles.

"Sometimes in my life I need advice," Joe told Ben and Susanna Reid while they were talking about Love Island's Curtis. "And I think he would be very handy."

"Like don't go to school in your son's trousers," Ben quipped.

"That's a cheap shot, that," Joe said, trying to keep a straight face. He then referenced Ben's team losing at Soccer Aid: "Unlucky about the penalty though. You lost."

"Let's go to VAR on the trousers," Ben quipped as Susanna laughed.

Joe walked off set, yelling: "Someone sort these trousers out, will ya?!"

Earlier, Joe opened up about his "tiny" baby son Rex, who he's said has put on weight since his premature birth last month and praised his "warrior" girlfriend and branded her "amazing".

He said: "He’s four weeks old my little boy. He is tiny. He was only a little tiddler but he’s put on loads of weight now so he’s back to birth weight so he’s ready.

"Stacey’s doing amazing. It’s such a difficult job being a mother. She’s a warrior. If it was down to us (men) we’d never do it. She’s doing amazing. Kids all love him as well."

Joe is also dad to 11-year-old son Harry with his ex-fiance, while Stacey has two sons; Zachary, 11, and Leighton, eight.

Yesterday Stacey shared a no holds barred post about breastfeeding after her Instagram followers quizzed her about her routine.

The mum-of-three said she was having to pump her milk throughout the day to make sure Rex was getting enough.

Taking to her Instagram stories, Stacey wrote: "Lots of people asking why I'm pumping so much... it's a long story, but I was told I had to.

"Baby wasn't feeding properly, and I don't think I got the latch right in the beginning which didn't help.

"My milk didn't come in until day 5. I was told I needed to give top ups after every feed and make sure he gained enough weight."

Stacey revealed that it had been "really difficult" to get the baby to breastfeed as he's getting used to being bottle fed, but she was perservering.

She continued: "Hopefully he will get bigger and suck harder and for longer enough so that I can cut out of all of the top ups.

"But he may not so we will just have to see how it goes."
