It can be exhausting trying to save the world, so it's understandable Bono would want to get away from it all with a sojourn in Saint-Tropez. But eyebrows have been soaring sky-high over who he's been spending his downtime with in the French Riviera. Last week, the do-gooder U2 front man was spotted in the heavily accented company of Penélope Cruz, with paparazzi following the pair as they perambulated on the beach hand-in-hand and partied together into the early morning hours. "They were very touchy-feely," a spy tells the London Daily Mirror. By the weekend, however, Bono was once again clasping the digits of wife Ali Hewson, his high school sweetheart and mother of his four kids. They even hit a Saint-Tropez hot spot where Penélope was hanging out with R.E.M.'s Michael Stipe. No word on whether Bono had some serious 'splainin' to do over his public chumminess with Cruz, whose rep didn't respond to our request for comment.

Was Jessica Alba's decision to eighty-six Cash Warren fueled by wedding fever? Although Us Weekly says the starlet ditched her boyfriend of two years over the phone by bluntly informing him, "I'm not in love with you anymore," loose-lipped pals insist to the New York Daily News that commitment issues actually did them in. "He wasn't ready for marriage, and Jessica is," tattles a source. "It's simple as that. It's kind of cold that the press is saying she was just finished with him, because it isn't like that." Alba, who was previously engaged to her "Dark Angel" co-star Michael Weatherly, purportedly began pining for a white dress after attending the Parisian nuptials of Eva Longoria and Tony Parker. "Seeing Eva get married made Jessica wistful," explains the insider. "That was the reason Jessica seemed to be in a terrible mood in Paris."

What is it about Pete Doherty that makes him so darn irresistible to the opposite sex? The pasty, perforated skin? The deep-seated dysfunction? The alluring musk of nicotine and stupidity? The Mail on Sunday says the rehabbing, recidivist rocker, 28, who was reportedly given the heave-ho by Kate Moss after he got up close and personal with a younger model, has reunited with onetime flame Nadine Ruddy, 23. "They do have a lot of history," a snitch tells the paper. "They dated before Pete met Kate and have remained very close. He confides everything to Nadine and she always soothes him and makes him feel better." Moss, for her part, "is doing everything she can not to crack and weaken," a pal blabs to the paper, "though there are dark moments when she breaks down and really misses Pete. She will be devastated to hear he is back with Nadine."

Is Keira Knightley ready to make a long-term commitment to beau Rupert Friend? No, not marriage -- mortgage payments. According to the London Sunday Mirror, the "Pride & Prejudice" pair is planning to pool their resources and buy a pad together. They reportedly looked at a few potential properties in a "trendy" part of London last week. Says a "pal of the couple," "They just got tired of living apart."

What do you get when you mix a hot new Los Angeles club with two very eligible bachelors? Apparently hookup central. The New York Daily News says Owen Wilson and Adam Brody were making the most of the jumping scene Thursday night at the opening of hot-spot-of-the-moment Opera. The crooked-nosed ex of Kate Hudson "had a few drinks, and at the end of the night he was sitting on a bench with a blonde whispering in his ear, sitting on his lap," a spy tells the paper. As for Brody, who's been playing the field since his split with Rachel Bilson last year, he was seen exiting with "a petite blonde."

In related news, Jim Carrey and Jenny McCarthy are inching closer to cohabitation. The blonde tells In Touch that she'll soon be setting up house in Beverly Hills, Calif., with her limp-locked A-list amour of two years. "I haven't moved yet," she says, "and I haven't hired a decorator, because my dream house will be exactly like the one I have now -- but with a 90210 zip code."

And in still more shacking-up talk, Neil Patrick Harris is moving in with his actor-boyfriend David Burtka, says Star. The Emmy-nominated "How I Met Your Mother" actor describes his new Los Angeles place, which is currently undergoing a major renovation, as a "big boys' house."

Sometimes a coupling is so bizarre it's almost gotta be true. Case in point: Joe Pesci and Angie Everhart, who are supposedly planning to tie the knot in the near future. The National Enquirer claims the diminutive, "Do-I-Amuse-You?"-asking Oscar winner, 64, proposed to the 37-year-old flame-haired former fiancée of Sylvester Stallone during a recent jaunt to Atlantic City, N.J., sealing the deal with a honkin' diamond ring. "Love blossomed after a seven-year friendship," a source tells the tab, "and finally Joe said: 'What are we waitin' on? Let's do it!'" While Pesci's people tell the New York Daily News the two are merely pals, the paper says the couple looked "cozy" as they holed up together in a suite at an Atlantic City hotel.
