Are two of the most physically perfect specimens in Hollywood getting to know each other better? The New York Post recently spotted Jessica Biel, she of the bulging biceps and backside you can bounce a quarter off of, on a "dinner date" in Los Angeles with six-pack-ab-sporting Ryan Reynolds. So were the "Blade: Trinity" co-stars just reminiscing about their days hunting vampires with Wesley Snipes, or is there something more afoot? Biel's rep didn't respond to our request for comment on the wooing whispers, but this isn't the first time the starlet, who was briefly linked to Justin Timberlake in January, and the actor, lately kaput with Alanis Morissette, have been seen together in recent weeks. TMZ also caught them chowing down on a less-than-health-conscious meal of burgers and fries following a pre-Oscar fete.

Speaking of Biel, does her ex-boyfriend have his eye on Emmy Rossum? That's the word from E's! Marc Malkin, who says Chris "Johnny Storm" Evans, otherwise known as the only appealing part of "The Fantastic Four," was checking out the Kewpie doll-faced starlet's tonsils last week at Los Angeles hot spot Teddy's. "They were making out in front of everyone," says an eyewitness. Rossum, 20, whom Us recently spied "making out like crazy" with formerly floppy haired "Heroes" star Milo Ventimiglia, reportedly hit it off with Evans, 25, when they met earlier this month. But Emmy's rep denies there was any spit-swapping going on, maintaining to Malkin, "They are just friends."

Good news for men who like their women apple-cheeked and statuesque (and can overlook a past dalliance with Wilmer Valderrama): Mandy Moore, 22, seems to be back on the market. The New York Post reports she's given the heave-ho to Adam "DJ AM" Goldstein, 33, after two months of togetherness, although a source "close to the pair" assures People the bust-up was "mutual." Moore, who split from Zach Braff last year, and Goldstein, the former fiancé of Nicole Richie, reportedly fell for one another over New Year's weekend in Miami. Soon, they were seen looking lovey-dovey everywhere from Los Angeles to the Sundance Film Festival. Mandy's mouthpiece is tight-lipped on the supposed split, telling the paper, "We don't comment on her personal life."

Ashlee Simpson is adamantly denying a report that she recently got up close and personal with Ryan Phillippe. When asked by shutterbugs this weekend whether rumblings that she'd hooked up with Reese Witherspoon's almost-ex were true, the remodeled starlet giggled before declaring, "Absolutely not!"

Was Pam Anderson trying to drop a major hint last month when she reminisced in a Web site posting about her insta-marriage to Tommy Lee as "one of the happiest times of my life," and bubbled, "Love is forever"? Paparazzi caught the recidivist exes tangling tongues after a recent lunch date at the Ivy in Santa Monica, Calif., with sons, Brandon, 10, and Dylan, 9, reports Us Weekly. Pam, 39, who finalized her divorce from Kid Rock in February, tied the knot with Tommy, 44, in 1995 during a beach-set, bikini-clad ceremony in Cancun following a week-long courtship (the rocker reportedly introduced himself to the bombshell by licking her face). They called it quits in 1998 but reconciled briefly a year later before finally parting ways for good. Back in January, Kid Rock allegedly attempted to confront Lee at a Las Vegas hotel after hearing rumors that he was spending time with Anderson, but he ended up banging on the wrong door.

What's a little handholding between well-preserved, well-coiffed former co-stars? Apparently not much if you're Heather Locklear and Jack Wagner, who have been joined at the digits while stepping out together in recent weeks. "[They] have been friends since 'Melrose Place,'" a Wagner insider tells People. "There's definitely no change in their relationship. They [just] went out with a bunch of her friends." Still, if Locklear, 45, the soon-to-be-ex of Richie Sambora, decides to pursue something with Wagner, 47, who divorced last year, her friends wouldn't mind. "He's super funny, charming, considerate and a little irreverent," a Heather confidante tells the mag. "I don't think anyone would be sad if [something more] happened."
