Valentine's Day 2007

A relationship that has managed to stay off the radar happens to be that of Heath Ledger and Michelle Williams. The two have been coasting along, deeply in love, but reportedly have hit their first major bump in the road called Lover's Lane.

Sources say Michelle and Heath had a huge falling out when Heath spent Valentine's Day with a bunch of other ladies at Teddy's nightclub in LA. Though the source says Ledger wasn't doing anything inappropriate, Michelle heard about it and freaked. She's reportedly giving him the cold shoulder.

Putting the bitterness of the divorce aside, actor Charlie Sheen spent Valentines Day with his ex-wife, Denise Richards, and their two daughters.

Following the official termination of their marriage on November 17, the two appear to have put much of the allegations and threats that surfaced during their struggle of a divorce behind them. The two had a seemingly enjoyable Wednesday afternoon, reuniting for a family day out with their children.

Amidst all of the troubles surrounding Paris Hilton, she just recently made some time to do a little Valentine's Day shopping....and it was not at Hallmark!

The visibly upset heiress was spotted shopping in Sunset Boulevard boutique Aahs, crying on her cell phone and saying: "I don't know what to do", according to the Sun.

"Paris was wearing her sunglasses and was dressed in a black tracksuit with a pink skull and crossbones on the back. She was going round the shop talking to someone on the phone and crying - she kept wiping her nose with a tissue," the shopper said.
