That sound you hear is single guys rejoicing from coast to coast. Or not.

Lindsay Lohan is back on the market! She broke up with Avi Snow!

Sources confirm to E! News that she and the rocker's brief, camera-friendly romance has ended, though the details of what led to their demise is unclear.

He said after his band City of the Sun's L.A. gig last week, before Lohan took off to go party in Brazil, that she was "really awesome" and "a lot of fun."

That's a nice way of saying crazy.

Things certainly seemed to be going well with the PDA pair, but then she split for South America and it's unclear if they have even seen each other since.
