Maybe 39-year-old Pamela Anderson & her 44-year-old ex-husband Tommy Lee are like a boomerang. You throw it into the world & it may be quite a while till it comes back to you, but eventually all things come back.

Anderson & Lee were spotted at the Ivy this weekend with their two sons, 10-year-old Brandon & 9-year-old Dylan. After the family exited the Santa Monica restaurant, Pam & Tommy had a very long lip-locking smooch, and from the looks of it, it was a very steamy one.

Are these lovebirds are back to their old ways? You tell me.
