UPDATE: No such luck…. the two are just buds! Too Fab has the scoop:

After some curious photos surfaced this weekend of the two looking very cozy during Ash’s birthday party, the rumors started — suggesting Efron had moved on from his ex-girlfriend Vanessa Hudgens with another “High School Musical” star, one who also happened to be one Hudgens’ best friends.

Moments ago, Tisdale responded to the Disney dating controversy, tweeting “Don’t believe all pictures. People r gonna come up with stuff to say bc it sells! I had such a great birthday party with my friends, Family, and BOYFRIEND Scott. I will not let stupid rumors ruin all the fun we had! Xoxo”

Anyone looking for more proof that the two are just friends need look no further than the photo below — showing Ashley getting a kiss on the cheek from boyfriend Scott Speer the night of the party.
