"We're crazy in love," says Tommy Lee, who recently helped roast his ex-wife Pamela Anderson on Comedy Central (left, in L.A. on Aug. 7). And they've been acting that way lately, kissing in nightclubs and taking a family vacation with sons Brandon, 9, and Dylan,
So will the pair (at the roast's afterparty) wed again? "Absolutely not," says Anderson, 38, who recently dated actor Stephen Dorff. Meanwhile, Motley Crue drummer Lee, 42, might have other intentions: "I want to finish what I started." (The two divorced in 1998 after three years, and in 2003 settled a bitter battle in which Anderson sought full custody of their sons.)
On vacation in Maui on July 10, Anderson and Lee hung out in the pool, played with Dylan and Brandon and reportedly smooched. "It was nice to have the family together," Anderson wrote on her Web site. "We don't spend much time with Tommy...We scared away a few paparazzi...(I) can't imagine what they'll come up with."
They arrived holding hands, then Anderson and Lee spent the night – when not partying with Dave Navarro and Carmen Electra – kissing in a booth at the June 30 opening of Rokbar in L.A. So how to define their on-again, off-again relationship? As Anderson once told PEOPLE: "You can't put a label on it."
Anderson was back in her ex's arms to watch son Dylan's baseball game on May 8 in Malibu. "The boys miss Pam and me together," Lee tells PEOPLE. "When we're together, they're so happy. At the end of the day, that's truly what my heart wants. I want us all to be together."
Since Anderson broke off her engagement to Kid Rock in 2003, she and Lee have been anything but shy with affection. The twosome – with Anderson's pup Luca Pizzaroni Pasquini – share a peck after grabbing lunch with the kids in Malibu on Jan. 15.
"They're the Liz Taylor and Richard Burton of our era," says Lee's Motley Crue bandmate Nikki Sixx of the couple, who married Feb. 19, 1995, in Cancun and then exchanged vows again in L.A. And despite their rocky track record (Lee battled alcoholism and was jailed for domestic violence), Anderson still has a soft spot for their marriage. Chiding him at her roast, she told Lee: "Those were the happiest years of your life."
