Chris Evans and Minka Kelly are back together, multiple insiders tell the new issue of Us Weekly (out now).

After dating briefly in 2007, the Avengers actor, 31, and the Roommate actress, 32, recently decided to rekindle their romance. "She did a number on him him back then," a source says of Kelly, who was serious with New York Yankees shortstop Derek Jeter, 38, from 2008 to 2011. "But she reached out to Chris this time."

As The Boston Herald reported, the on-again actors hit Max and Dylans eatery in Evans' hometown August 18. They took in the musical The Book of Mormon in New York City six days later. Still, pals hope Evans — who romanced his London costar, Jessica Biel, 30, from 2004 to 2006 — doesn't get burned again.

"He's still a little insecure, so he's being cautious," one Evans friend says.
