Joe Jonas and Ashley Greene: B-Day Shopping for Frankie!

Reunited now that he's finished up touring with his brothers, Joe Jonas and Ashley Greene were hand-in-hand in Los Angeles, CA on Tuesday (September 28).

The JoBros rocker and his "Twilight" actress girlfriend looked happy to be together as they partook in a bout of shopping at the local Walgreens.

As for the reason behind the trip, Joe was grabbing a last minute card and gift for little brother Frankie Jonas - who happens to be celebrating his 10th birthday.

Meanwhile, Miss Greene is enjoying her little remaining free time - as she's set to get to work on "Breaking Dawn" next month with the two-part movie expected to be shooting through April 2011.
