George Clooney's kids saw him kissing Julia Roberts for their new rom-com, and they were very confused

• George Clooney and Julia Roberts play ex-spouses in the romantic comedy "Ticket to Paradise."
• They filmed a kissing scene on the first day of shooting as Clooney's family came to visit.

George Clooney said kissing his real-life bestie Julia Roberts on-screen got awkward when his family visited the set in an interview with Hoda Kotb for the "Today" show.

Clooney, 61, and Roberts, 54, costar in "Ticket to Paradise," playing warring exes who conspire to sabotage their daughter's upcoming wedding. The two recalled to Kotb how they shot a kiss scene on the first day of filming, when Clooney's wife, Amal Clooney, and 5-year-old twins, Alexander and Ella, were there to visit.

"That was the first day they came to visit. It's like 'papa ah, Auntie Juju'," said Roberts.

Her solution was to send the kiddies packing. "It's like get 'em out! Get 'em out," she continued.

"It's really bad," added Clooney, who clarified that "they weren't around" during the actual take of the scene.

He joked that his kids would have asked, "What are you doing papa? What is that?"

Roberts said that kissing Clooney felt ridiculous due to their long-enduring friendship; they have known each other for over 20 years and were first paired on-screen in the 2001 remake of "Ocean's Eleven."

"It took 79 takes of us laughing and then the one take of us kissing," she said.

Clooney confirmed that they were all laughs but mocked offense at her immunity to his heartthrob status. "Well, thanks for that," he said. "You know I was a two-time 'Sexiest Man Alive?'"

"Ticket to Paradise" is in theaters October 21.
