Deciding to stay mum on Brooke Mueller's recent drug/assault arrest in Aspen Colorado last weekend, Denise Richards simply smiled as she shopped in Beverly Hills, on Monday.

The Wild Things star has publicly supported Mueller in the past, telling Extra in July, "I give Brooke a lot of credit. I know that she's struggling with her addiction and she wants to be the best mom she can be."

The celeb moms may share an ex-husband, Charlie Sheen, but Denise seems more interested in a quiet life raising her three daughters, while Brooke just can't seem to let go of her hard partying ways.

The troubled mother of two-year-old twins Max and Bob -- who were also in Aspen during the incident -- checked out of her most recent rehab effort in July.

Mueller was released from Pitkin County Jail for suspicion of assault and possession of cocaine with intent to distribute, after Sheen allegedly posted $11,000 bail on Sunday.

A hearing is set for Dec. 19.

Bon Jovi's Richie Sambora and Denise Richards have rekindled their romance, according to Us Weekly.

The twosome have been seen going on several dates in recent weeks.

Sambora, 52, and Richards, 40, first began dating in 2006. They split back in 2007 after Richards was accused of breaking up Sambora's relationship with Heather Locklear.

A source tells the mag:

"They've always stayed friends, through everything they've gone through. He's had a rough patch, she's had her own stuff but they're both in a great place right now."

The source adds that the couple is "doing great and happy."

Their reps have yet to return our requests for comment.

There's no stopping Denise Richards! This busy mama of three is taking a break from mommy duty to film a stint on 30 Rock with a very affectionate white dog. Adorbs!

We all know Charlie Sheen's ex is gorgeous, but over the years she's proven that her comedic timing is top notch, too.

Dressed in a leather jacket with animal print, pink scarf and letting her hair flow free, Denise looked picture perfect on set alongside series regular Tracy Morgan.

Denise Richards

Denise Richards announced that she'd adopted new baby girl Eloise in June, and now the actress is revealing the thought process behind her decision.

She explains on her new blog that she started the process two years ago, saying:

"I had always wanted to adopt and had always wanted more children. I needed to make a decision: Do I wait for the right partner or move ahead with my life and do it on my own? I decided to do it on my own."

Richards already had daughters Sam and Lola from her marriage to Charlie Sheen. She recalls that the two-year process was rough. " ... there were many times during that I felt discouraged," she says. "But I always had faith that the right baby would find us (my daughters and me)."

Twitter

Eloise may only be just a few months old, but she's already a budding fashionista!

Proud mom Denise Richards shared a Twitpic of her darling daughter sporting a pair of $265 Baby Gucci Jeans, with the caption: "Eloise rockin her jeans".

The Wild Things star dressed her girls up to attend a screening of the X Factor at the exclusive Pepsi House in LA, and it appears her girls already have wardrobes that could rival Suri Cruise's.

In other news, Denise's ex-hubby Charlie Sheen recently purchased a home in a gated Malibu community for his family, just six doors down from his own place. Sheen purchased the home so he can visit with daughters Lola, 8, and Sam, 7, as much as possible.

Richards and the kids are expected to move into their new Malibu pad by next week.

Denise Richards is a certainly a multi-tasking mama! The Wild Things star picked up daughters Sam and Lola from tennis lessons in Thousand Oaks, and as always, the 40-year-old actress looked fab!

Charlie Sheen's ex-wife left three-month-old baby Eloise at home while she spent quality time with her two older girls. Ms. Richards certainly knows how to spread her love evenly with her growing family .... while balancing her career at the same time.

Although Denise looks gorgeous, we can't help but notice her extra plump lips. She's always had full, luscious lips, but they're looking mighty large these days. Now THAT'S lip service!

The season premiere of Two and a Half Men had tons of guest stars, but Charlie Sheen's ex-wife Denise Richards was not one of them. But apparently, the show wanted her there!

Producers were hoping to have Denise, 40, play one of Charlie's exes during the opening funeral scene and would have paid her $100,000 for the role, according to Life & Style. "They wanted to bring back a real ex," a source told the mag.

Though word is that Denise does want to be on TV again, she knew that it wouldn't be in her best interest to make an appearance and ultimately said no to the offer. "Charlie would've gone crazy, and Denise knows where her bread is buttered," the insider said.

A bad idea? Maybe. But would it have been hilarious? Definitely!

Our hearts are melting!
