Just months after calling it quits with boyfriend Scott Speer, Ashley Tisdale and the Step Up Revolution director are giving their relationship another try.

A source tells E! News the 26-year-old High School Musical star and Speer have been back together for at least the last few weeks, and it looks like they've picked up right where they left off.

We're told the couple spent all last weekend together as sort of their "coming out" to show they had officially reunited.

Tisdale's 29-year-old, on-again beau even offered up a sweet tweet recently when ABC entered into a development deal recently with the Blondie Girl productions owner for her detective drama pilot, The Keys

"CONGRATS! Blondie Girl is taking over!," Speer tweeted to his ladylove, to which Tisdale replied, "hope you have a great day today!!!"

The couple, who broke up last December, has been dating since spring 2009.
