Jamie invited the TOWIE star onto his show In Bed With Jamie, which features on the Channel 4 website.
The star has had a number of names, including Pamela Anderson, on the series.
This week it was the turn of Megan, as well as former Made in Chelsea star Spencer Matthews.
Jamie headed to meet Megan at her new bar and restaurant McK Grill.

Asking her all sort of things about TOWIE, Ex on the Beach and her new business, Jamie had plenty to talk about.
But Megan had no idea Jamie had something else up his sleeve, and the entire interview was a set-up.
Jamie had a number of pranks lined up in order to see if he could make Megan get mad.
Megan is known for her outbursts, as seen on Ex on the Beach and Celebrity Big Brother, with the star admitting people thought she was a “psycho”.
But as he continued to test her patience, was Jamie going to get the reaction he planned?
First off Jamie was seen moaning about his crew, with the sound guy even chucking his microphone boom at her before walking off.

She asked Jamie: “Is he alright,” as Jamie pretended to be baffled by the moment.
The crew member then returned and asked Megan for a selfie, leaving her in shock that he would disrupt the interview again.
He then took the photo before walking away, but this was the least of her problems.
As Jamie asked her about the launch of her restaurant, she told him the interview was adding to the stress and said: “This is very stressful, I didn’t think it would be this stressful.”

Jamie then interrupted the interview twice to speak to his “mum” on the phone, leading to Megan pulling a string of hilarious faces.
Clearly annoyed, Megan sat and waited for him to finish his phone conversation only for it to happen again.
This was then followed by loud bangs coming from the kitchen as the crew continued their work to finish the venue.
Jamie then stormed off during the interview, telling Megan he had to go before blasting the crew – with one of them then having to step in and continue the interview.

Megan was fuming as Jamie fled and the interview was ended, before a parcel was delivered to her and left in the middle of the restaurant – and this was the final straw.
But Jamie then jumped out of the box and revealed it had all been a prank to wind her up!
