Lindsay Lohan’s new boyfriend was engaged. . .until he met her.

Lohan met the loser in rehab, of course. How romantic, they can do lines off each other’s privates. Anyhow, his name is Riley Giles and he’s a snowboarder. . .and obviously an asshole.

Riley was engaged to Bree Tierney from Murray, Utah, who got a hard lesson in life after she was dumped for the coke whore of Hollywood. That’s gotta hurt.

Bree’s mom tells Us Weekly, “Riley just stopped calling Bree and never told her about Lindsay. She found out by seeing photos. It destroyed her.”

A source tells Us that Riley is a bad boy with a wild past. “Lindsay may be in danger with Riley.” After exiting rehab the new couple immediately hit a nightclub in Salt Lake City.

Owner Jordan Harwood tells Us, “Her group made it clear they didn’t want any alcohol at the table.” But one source says that’s a crock and that she was indeed drinking.

Lindsay’s not only a home wrecker, she’s also not very smart. NEVER do you hookup with someone from rehab when you are trying to get well. Unfortunately I have seen people do this, and I’ll tell you, it never works out, and usually it ends in something terrible. It’s just a fact.

Hopefully Lohan will kick men to the curb for the time being and realize this time is hers. For blogs sake, she’s only 21. . .there’s plenty of time to get her firecrotch extinguished.
