Aussie actor Liam Hemsworth was spotted leaving an Oscars after-party with ex-Disney starlet Ashley Tisdale on Sunday night.

Ashley, 25, and Liam, 21, were spotted leaving Boa Steakhouse in Los Angeles together, after attending the InStyle magazine Oscars after-party, with Liam having a "protective" hand on Ashley's arm, the UK's Daily Mail reported.

While the pair's reps are yet to confirm the romance, we're betting Miley Cyrus (who dated Liam and is Ashley's BFF) is fuming!

The number-one rule of a friendship? Never date a friend's ex.

Sure, Miley and Liam officially ended it last year, but do you think Liam and Ashley hanging out is totally crossing the line?
