As the news spread about Pamela Anderson and Kid Rock's mutual divorce filings
after less than four months of marriage, friends have expressed their support – and their surprise.
Denise Richards, who just finished working with Anderson on the movie Blonde and Blonder
in Vancouver, tells PEOPLE about her costar: "My thoughts are with her and her boys. Pam is a very strong woman and will get through this difficult time."
Traver Rains and Richie Rich, the New York City-based designers behind the fashion line Heatherette – who designed the dress Anderson wore at her St. Tropez wedding in July
– say they were caught off guard by the news.
"Maybe it's a spat," Rich tells PEOPLE. "They're so in love, and I'd be surprised if it was over forever. I don't think she'd let her prince go."
Rich says he spoke with Anderson recently and she showed no signs anything was amiss in the marriage. "I thought they were the perfect couple, so in love, so happy," he says. "She found Prince Charming. I hope he didn't turn into a frog."
What made them work so well? "They're very energetic, they have that glow, that sparkle," says Rich. "Beyond Hollywood, they're such a good combination. They were such lovebirds. They're adorable."
He recalls, "She was so excited getting her dress and about St. Tropez. The rock star and the sex goddess – it's hot. They don't come along like them very often."
"I know Pamela's obsessed with her kids," says Rains. "They're always at the forefront of everything she's thinking about." Echoes Rich: "They share the love of kids."
Anderson has two sons, Brandon, 10, and Dylan, 8, with her ex-husband, Mötley Crüe drummer Tommy Lee. Rock has a 13-year-old son, Bob Jr., with former flame Kelley South Russell.
"Everyone thinks Pamela's just a bombshell, but she's a mom going to soccer practice," says Rich. "When I met him, Kid Rock was flying home to go to a chorus concert with his kid. It's the best of both worlds."
"I think that's what made the deal with the whole marriage – Pamela wouldn't have married him if he wasn't for his kids and vice versa," he adds. "Their kids come first."
