In real life he happily attended their wedding just days ago, but in a preview clip for the newest episode of Wahlburgers, chef Paul appears to be anything but comfortable in the presence of his brother, Donnie, and his fiancée, Jenny McCarthy.

Paul The Butt Of Everyone's Jokes?

The episode, which covers Donnie's New Kids on the Block tour in England, shows him feeling homesick for his family-and Jenny convincing Paul to step up to the plate and come visit his brother.

"Going on tour in a foreign country is always difficult," Donnie says in a preview clip for the Wednesday, September 3 episode.

With that, Jenny sneaks away to place a phone call to Paul.

"He misses his family," she says.

"Let me see what I can do," Paul replies from Boston.

However, though he tries to be a good brother, Paul may soon regret his decision to come to England, as the trip winds up being something he didn't expect-as he deals with Jenny putting on a fake British accent, Donnie being overly affectionate, and experiencing foods that Donnie insists he loves-but he doesn't actually care for-like Spotted D-k, a Mutton fat pudding.

"Paul meets Donnie and Jenny in a strange land known as England," a voiceover narrates in the clip. "He'll engage in awkward activities, eat exotic food, and root for his favorite boy band."

By the end of the trip, Paul may be regretting his decision.

"It was really uncomfortable," he says.

Wahlburgers airs Wednesdays at 10 p.m. on A&E.
