It's been a week for love and gossip in the wild world of celebrity, although some star's love lives are not running so smoothly.

Well, Usher, it looks like mama was right all along. The baby-faced crooner, 30, filed for divorce from Tameka Foster Raymond, his 38-year-old wife of two years. His mother's opposition to their relationship caused some very public problems for the couple. After their lavish wedding was canceled due to issues with his mother and bride-to-be, Usher's mom skipped their civil ceremony marriage. Now, after the birth of he and Tameka's two baby sons, he may have decided that mamma Jonetta Patton was right from the start. Meanwhile, Tameka's lawyer has denied any wrongdoing on his client's part, saying she was a good wife to Usher and a devoted mother to his children.

Fortunately, celebrity love marches on. Bruce Willis is loud and proud when it comes to his new wife, model Emma Heming. Heming, 32, and Willis, 54, married in March 2009. They recently celebrated their love in a unique style - with a racy photo shoot for W Magazine, due to come out next month. In other news, Joshua Duggar, the eldest Duggar son, is already following in his parents' famous footsteps. He and wife Anna married in September 2008, and are already expecting their first baby. It's a girl!

Lindsay Lohan and lover Sam Ronson have crashed and burned once again, and Lohan's subsequent behavior is increasingly bizarre. Most recently, the actress sent a scandalous photo of herself to followers on Twitter. Not helping: the fact that $400,000 worth of jewels recently went MIA during a recent Lohan photo shoot with Elle magazine, prompting some people to wonder if Lohan herself was to blame.

All in all, Hollywood has been delightedly dysfunctional this week. Hopefully, some of the bumps will be smoothed and our stars will live happily ever after.

Fickle celebrity hearts are fluttering this week with break-ups, make-ups and the inevitable cheating heart. Last week, reality TV star Jon Gosselin was accused of cheating on Kate, his wife and mother of his eight kids. According to People magazine, he was quick to deny these accusations, claiming that mystery woman Deanna Hummel is just a "female friend." It seemed like the accusations of infidelity might be put to rest, but alas - it seems like Jon may have been less than honest. New pictures and video have emerged online, including one picture of Ms. Hummel sunbathing in a bikini on his lawn while Kate was away. The most damning evidence, however, is a video taken of Jon apparently leaving Ms. Hummel's house around 7:00 a.m. The strangest thing yet? While everyone else, including Jon, Ms. Hummel, her brother and his friends, have spoken out about the "affair," Kate Gosselin has yet to say a word. Now, if he weren't cheating, wouldn't she want to clear her husband's name?

The world's most famous on-again, off-again lover Lindsay Lohan and Samantha Ronson, seem to be on again (at least for the time being). Although she's been seen spending the night at her (ex?)girlfriend's house, neighbors say they scream at each other almost non-stop, according to the Daily Mail. I could be wrong, but it seems yet another break-up is in the works for LiLo and her DJ gal pal.

Poor Elizabeth Edwards appeared on The Oprah Winfrey show this week to talk about her husband John Edwards highly-publicized affair. According to People magazine, Elizabeth, who threw up when first confronted with the news of her husband's affair, is still trying to make it work. This is due in large part to John Edwards support as Elizabeth battles cancer. However, when Oprah asked her if she still loved her husband, her answer was less than clear. "You know, that's a complicated question."

Did you ever wonder why seemingly-happy couple Lance Armstrong and Sheryl Crowe split? Turns out, it was just a matter of timing. In a new book, Lance opens up about their relationship, claiming it was not unhappiness but her biological clock which caused the split right around her 44th birthday. "She wanted marriage; she wanted children; and not that I didn't want that, but I didn't want that at that time because I'd just gotten out of a marriage, I'd just had kids." It's good to see that at least one Hollywood couple parted on good terms.
