OK! spotted the unlikely pair, dressed casually in jeans, leaving the Hollywood Roosevelt through a side door at 12:35 a.m. Thursday morning. Slipping unnoticed past a small crowd of partygoers, the low-key duo walked across the street and decided to bypass busy Hollywood Boulevard by strolling down an adjacent alleyway.
“Heidi appeared to be leading the way,” one onlooker tells OK!. “She and Steve were exchanging the odd word as they crossed the street but got more chatty as they disappeared down the alleyway.”
Earlier in the evening, Heidi stopped by the nearby launch party for the Samsung Blackjack II at Eva Longoria’s soon-to-open eatery Beso.
In January, Steve, who in addition to being linked romantically to the former Mrs. Tom Cruise, has a son with British actress Elizabeth Hurley and hid out at reports that onetime flesh peddler Heidi set him up on a date with then-single actress Pamela Anderson.
