Jennifer Aniston and fiancee Justin Theroux apparently go on sexy vacations with celebrity friends like Jimmy Kimmel and Howard Stern... and Jimmy Fallon is feeling left out. The Tonight Show host confronted Aniston about her 'champagne and caviar trips'. The Cake actress then engaged in a bit of lip swapping for the latest round of 'Lip Flip', and Aniston — wearing Fallon's lips — revealed she's 'bought tickets to Bonaroo'! But why is her fiancee painting pictures of zombie babies?

As Aniston points out, she's sick of being interviewed, so she'd rather interview herself, prompting a killer version of 'Lip Flip'. It offers such gems as Aniston putting on an incredible surfer/valley girl accent and talks about "buying tickets to Bonaroo," where she'll eat "mac & cheese in a tent."

Fallon, for his part, is a "pretty, pretty, pretty little thing ya'll."

They also swap NFL Super Bowl picks! Check it out:

Earlier, after being confronted about her sexy vacations with her fiancee and celebrity pals Howard Stern and Jimmy Kimmel, Aniston pointed out that she'd "love to see" Fallon in a mankini," but refuted the idea that their getaways are all "Champagne and caviar."

"Honestly," the Cake actress says, "it's a very low-key group. The boys this year sat around and did arts and crafts."

Really? They sure did, she confirms. "They honestly sat around and Howard is painting these days, like beautiful landscapes and flowers, and he's really good. He's multi-talented."

Aniston also answers the big question as to whether Howard gets some sun. "He doesn't lay out," Aniston unsurprisingly confirms.

But back to the painting. "It was adorable," describes Aniston. "You know, girls usually sit around beading and making necklaces, it was just the guys hanging around doing artwork and I loved it."

So what does Stern paint? "Vistas, he takes pictures, or flowers... anything he sees that inspires him."

How about Kimmel? "Jimmy is an incredible artist. He takes pictures off the internet and draws them..."

Her fiancee Theroux? "Justin draws pictures of zombie babies. It's a little insight. Crazy monkeys and stuff like that, dead people. He went to art school. It gives you a little insight into all of their personalities. It's quite lovely."

How nice.

Aniston also spoke about her new movie Cake, talking about addiction, saying "it's a struggle."

But the movie itself, she adds, is surprisingly funny. Check out the interview below:
