Abigail Breslin, 17, Dating 25-Year-Old Musician Jack Barakat

E! News confirms that the couple "just started dating"

Little Miss Sunshine is all grown up and has a boyfriend!

Fans have seen young actress Abigail Breslin mature on the big screen, and now E! News has learned that the 17-year-old, blue-eyed beauty is dating 25-year-old All Time Low vocalist Jack Barakat.

A source tells E! News that the couple, who were photographed together at the Los Angeles premiere of Breslin's sci-fi flick Ender's Game last week, "just started dating," also adding that Barakat "visited her on the set of her new movie" Maggie.

Breslin's rep had no comment.

The celeb and Barakat first met at an All Time Low concert back in April, according to Us Weekly (who first broke the story). During the film premiere party last week, Breslin reportedly mingled between her younger pals and the "adult section" at the event with her new beau in tow.

The teenage star talked to E! News about fans recognizing her from her younger roles while on the red carpet for the Teen Choice Awards in August.

"It's always shocking when people do recognize me from Little Miss Sunshine because I look so different," Breslin told us. "It's interesting because they're like, ‘You just look so much older.' I'm like, ‘Thank you, I guess.'"
