Look out, guys. Lilo's single again!

According to TMZ, Lindsay broke up with Riley whatshisname, her snowboarding rehab boyfriend.

Awww. And they looked so happy over the holidays in New York.

That's harsh. Poor dude didn't even last long enough to get his name listed on LiLo's WireImage pages.

Lindsay, honey, you did the right thing. Just ask Elizabeth Taylor: Rehab relationships don't last.

Does the name Larry Fortensky ring a bell?
