Minka Kelly and Chris Evans are back together. The Roommate actress and the Avengers actor dated briefly in 2007 but have decided to give things another go and recently rekindled their relationship.

"She did a number on him back then. But she reached out to Chris this time," a source said.

However, Chris wants to take things slowly as he doesn't want to get hurt again. "He's still a little insecure, so he's being cautious," the source added.

Chris - who has previously dated Jessica Biel - recently said he wants a girlfriend who isn't afraid to argue with him and is not bothered by his celebrity status. "I like ... girls who give me a hard time [and] bust my chops a little. I like girls who aren't so la-di-da. L.A. is so la-di-da. I like wet hair and sweatpants. I like sneakers and ponytails," the 31 year-old said.

Mika, 32, was recently liked to actor Jake Gyllenhaal after the pair went on a string of dates together and was previously in a long-term relationship with Derek Jeter.
