Lindsay Lohan, who was most recently seen stalking her ex-girlfriend Samantha Ronson in London, was spotted catching a flight from London to to L.A. yesterday with Samantha Ronson and wearing a suspicious looking diamond ring. Is this a good idea?

The actress -- who told Us Weekly she was "so alone" after her April split from her DJ girlfriend -- was spotted in London with a diamond ring on her left hand (where engagement rings are usually worn, although she had it on her third finger instead of ring finger).

Lohan was cryptic on her Twitter page. "Leaving London but but with my favorite favorite!!!-travel buddy & great news to share!! Maybe…." she wrote. (Source)

Great news to share maybe? You mean if Samantha's drugs don't wear off first before she gets a chance to break it. The only thing stupider than getting engaged to Lindsay Lohan would be joining the Chinese mafia. And even that would probably be easier to get out of.
