Brooke Mueller is so stressed, she telling friends her life is "a living hell," RadarOnline.com is exclusively reporting. And Charlie Sheen's estranged wife has turned to none other than Kathy Hilton for support.

"Brooke is leaning on Kathy," a well-placed source tells RadarOnline.com. "She's spending a lot of time with Kathy especially when she has the kids.  Bob and Max even call her 'Aunt Kathy'."

Kathy Hilton has known Mueller for the last few years and has grown close to her since Brooke signed on to costar in her daughter Paris' new reality show for the Oxygen network.

As RadarOnline.com exclusively reported, it was even Kathy who convinced Brooke to go back into rehab several months ago.

Along with her sober coach, Brooke and her boys spent much of Thursday with Kathy, RadarOnline.com can exclusively reveal.  It was just after 10 pm on Tuesday that police and Mueller's legal reps went to Sheen's home and removed Bob and Max, returning them to Brooke.

Hilton is very protective of Brooke and trying to help her in any way she can, our source tells us.  "She loves Bob and Max," the source says, so she's more than happy to support Brooke out with their care.

House actress Lisa Edelstein has moved into the political arena as she takes on the G.O.P. in a new ‘right to choose’ ad made in conjunction with activist group MoveOn.org.

The 43-year-old, who plays Dr. House’s love interest, Dr Lisa Cuddy on the Emmy award winning drama, stars in a new 30-second TV ad as a woman who is forced into a “back alley” to undergo a pregnancy termination.

The message is a direct attack on what MoveOn.org claim is the Republican party’s assault on women’s health and their right to choose.

The ad opens with Edelstein dressed in 1950s-era clothing walking shakily down a hallway towards a door as you hear her voice saying: “Decades ago, women suffered through horrifying back alley abortions. Or, they used dangerous methods when they had no other recourse.”

And it ends with a terrified Edelstein, dressed in modern day clothing, tearfully opening a closet door to reveal a wire clothes hanger, a scene symbolically associated with the dangerous situations women were forced into before they gained reproductive rights.

Edelstein’s voice then asks: “Why is the G.O.P. trying to send women back to the back alley?”

The actress, who is an outspoken advocate for women’s rights, as well as a volunteer for the Best Friends Animal Society, Save the Children and Planned Parenthood, explained her decision to star in the ad: “I decided to do this ad because I believe that every woman needs to know the grave danger that women’s reproductive rights are facing in Congress right now,” she said.

“

I hope that women across America tell Congress that these bills are an attack on women’s health and that they are unacceptable.”

“

This ad is a wakeup call,” said Kat Barr, Campaign Director at MoveOn.org.  “If Republican proposals go through, women could once again face fear and danger when it comes to their reproductive health.

Just hours after RadarOnline.com revealed that her good friend Brooke Mueller was spending her nights in a sober living facility, Paris Hilton was out with boyfriend Cy Waits and mom Kathy for an arm-in-arm stroll through The Grove shopping mall.

Paris is starring in a new reality series for the Oxygen network.  It's all about her jet-setting life and features her mother Kathy Hilton as well as three of her closest friends.

Charlie Sheen's estranged wife, Brooke Mueller, is one of those friends, but as of Friday, she's been back at a sober living house, at least at night.

As RadarOnline.com reported, Brooke, who has twin boys with Sheen, became concerned about maintaining her sobriety and decided to seek help.  She had become "depressed," a source told us, facing Christmas -- the anniversary of when Sheen attacked her -- and didn't want to fall back into old habits.

She'd already shot several scenes with Paris, and the show will go on.
