LINDSAY AND WILMER: SAME CITY, WORLDS APART
Though Lindsay Lohan and her ex Wilmer Valderrama were both in New York City last week—she hosted Saturday Night Live, he promoted That '70s Show—they managed to carefully avoid each other at the clubs. ("That was on purpose," a pal of both tells us.) After midnight on May 20, Valderrama left his own Heineken-sponsored event early to party with Ashlee Simpson in a private room at AER (a Simpson rep says they are "good friends, period"), while just half a block away, Lindsay celebrated at Level V. Two nights later at SNL's afterparty at Rock Candy, Lohan chatted until dawn with Jared Leto (Lohan's rep says they're only friends), white Valderrama again hung out with Simpson, this time at Cellar Bar. Lohan's and Valderrama's paths did cross: The night of May 22 at Lotus, Lindsay whispered to pals when Wilmer walked in, joined soon after by Ashlee. On May 23 Lindsay and Wilmer ignored each other once again at Butter.

TRISTA AND RYAN TEST THEIR TALENTS
Ryan Sutter's dream of returning to the NFL at age 30 was short-lived: After trying out for the New Orleans Saints in early May, the former safety for the Carolina Panthers tore his Achilles tendon and will be recuperating for several months. "It was demoralizing," he says. Meanwhile wife Trista is in L.A. to shoot ABC's reality show Dancing with the Stars. "She likes dancing," Ryan tells us. "For me, it doesn't matter if I'm on crutches or not—my dancing won't improve."

SURVIVOR AND ANATOMY STARS ALIGN
Grey's Anatomy hottie Katherine Heigl and Survivor: Palau stud Gregg Carey hit it off when they met each other at Manhattan club Cain May 17. With Carey's on-island squeeze Jenn Lyon nearby, Heigl asked Survivor contestant Stephenie LaGrossa if Gregg and Jenn were still an item. She was told they're just pals now. Two hours later, at 2:30 a.m., Heigl and Carey left together, and the next day they dined at Rue 57. A source tells us the two have been phoning and "continuing to get to know each other."

MISCHA: I'M STILL WITH BRANDON
Despite persistent breakup rumors, Mischa Barton says she's still dating Brandon Davis—even though they're 6,000 miles apart. "Everything is great [with us]. Don't believe the things you read," says Barton, now in Siena, Italy, filming The Decameron with Hayden Christensen. After returning from Cannes, where she promoted the upcoming comedy, The O.C. star only ventured away from the set to tour a local chapel with Christensen and visit a new Fendi store in Rome with her mom, Nuala. "I didn't see anyone around her acting like a boyfriend would," says an Italian source. Meanwhile Davis has kept an extremely low profile back home in L.A. since Barton left for Italy in March.
