Drew Barrymore gets a blast from her past on the third season premiere of her talk show Sept. 12.

Justin Long, who dated the actor from 2007 until 2010, visited “The Drew Barrymore Show."

“I feel like we’ve been through so much together, too,” Barrymore said while crying in a preview clip released by the show.

I felt like when we used to talk and FaceTime, I was always like, you know, ‘I’ve really grown up, Justin.’

 I always wanted to prove to you what a different person I was than when we dated.

“We had so much fun,” Barrymore said. But we were more hedonistic, more immature.

We would get together. We would break up. There was chaos. It was hella fun.

“Fun chaos,” Long said. “Most hedonism is fun.”

Barrymore, 47, and Long, 44, co-starred in “He’s Just Not That Into You” in 2009, as well as 2010’s “Going the Distance.”
