Pamela Anderson, 39, and ex-hubby, rocker Tommy Lee, 44, may have ended their high-profile marriage in 1998, but could the two be looking to rekindle their romance?

The duo was spotted lunching as a family – with sons Brandon, 10, and Dylan, 9, – at the trendy Santa Monica eatery The Ivy this week.

Pam, who split from Kid Rock, 35, last November after four months of marriage, was snapped by photogs in a steamy smooch with Tommy as she exited the restaurant. No word yet on whether the two are back into their old ways, but one thing is for sure – that liplock is H-O-T!
