Is Bruce Willis in the midst of a bizarro midlife crisis? The New York Daily News says the bald-pated star, who tends to prefer his women on the dewier side, rang in his 52nd birthday last week by polishing the tonsils of (yikes!) Courtney Love, 42, while grooving to the smooth stylings of British chanteuse Amy Winehouse at the Roxy in Los Angeles. "They were full-on making out," tattles a spy, apparently after dousing their eyeballs with copious amounts of Visine. This is the second high-profile smooch session Willis has reportedly enjoyed in recent months: In January, he and Drew Barrymore "were making out in front of everybody" at a post-Golden Globes soiree, according to the paper. The actor's rep had -- shocker -- no comment on his alleged Courtney coziness, while her flack brushed off their tongue tangling as "a quick hi, and then they went their separate ways."

Turns out Paul McCartney's acrimonious split from Heather Mills hasn't soured him on the fairer sex. The former Beatle, 64, was seen last week in London squiring moneybags beer heiress Sabrina Guinness, 52, to dinner with his daughter Stella and her husband, Alasdhair Willis, a double date that was unfortunately foiled when paparazzi caught them together. Paul, however, is pouring cold water on speculation that he's dipping his big toe back into the dating pool. "I realize everyone wants to see me with a new bird right now and that's very flattering," he told the London Daily Mail. "I have known this lady for a while. We enjoy each other's company. When we get together we talk about stuff like the environment and Al Gore, things like that. We have similar views." But, he downplayed, "It's not really a big thing." Guinness was a bit more straightforward, declaring to the Daily Mirror, "We've been friends for a long time ... There's no relationship." Mills, meanwhile, was "apoplectic with rage" over the rendezvous, according to the Mail. "She feels this has really humiliated her. Heather has long believed forces are at work trying to destroy her and she feels this is just the next step," a confidante tells the paper. "In Heather's mind, she feels this has actually been done when she is out of the country to overshadow her American television debut [on 'Dancing With the Stars']."

Kid Rock, recently divorced from Pam Anderson, and Adam "DJ AM" Goldstein, back on the market after a brief romance with Mandy Moore, have both apparently landed new models. People reports Kid is seeing Danish mannequin May Andersen, who accompanied him to Elton John's birthday concert on Sunday in New York. "They are dating," an insider tells the mag. "They're having a lot of fun together. May dated [scrotum-stapling 'Jackass' buffoon] Steve-O -- she likes rocker guys. And I hear he's really caring, really sweet." DJ AM, meanwhile, has been seen in the company of model Jessica Stam, says the New York Post. "AM was really in love with Mandy," a source tells the paper, "but they had such different lifestyles, and they couldn't make it work."

"I think I'm too busy for men. I'm a single girl right now." That's Mischa Barton, putting on a stiff upper lip while chatting with the London Sunday Mirror following her instant uncoupling with model Jamie Dornan, best known as the guy Keira Knightley drop-kicked before taking up with Rupert Friend. The paper says the fashion-flawed starlet took a shine to Dornan when she landed in London last week to fulfill her spokesmodel duties for Keds, but the budding romance quickly fizzled after he stood her up at a nightclub. Barton, who is on the rebound from her split with longtime love Cisco "Droopy Drawers" Adler, remains optimistic about her romantic prospects, teasing the paper, "I'm hoping to spend more time in England, so who knows about the future and if the right guy came along."

Speaker of Adler, did he and his ex Kimberly Stewart have a warm and fuzzy reunion or a cold and discomfiting red-carpet run-in last week at a Details bash in Beverly Hills, Calif.? A spy tells the New York Post the former flames reconciled following several years of "frostiness," insisting they "looked totally cozy, just like in the old days." But a mole tells the New York Daily News that the hirsute rocker and Rod's talent-challenged daughter, who after her bust-up with Adler altered her "Daddy's little girl loves Cisco" tattoo to read "Daddy's little girl loves disco," "sort of took an awkward photo, but then ignored each other."
