Bijou Phillips, 43, shows off her pert derriere as she parties at a Grammys event with Kimberly Stewart – days after rapist ex Danny Masterson was moved to maximum security prison that once housed Charles Manson

Bijou Phillips, 43, showed off her pert derriere in a sheer black dress as she partied at a Grammys 2024 viewing event in Los Angeles.

The estranged wife of convicted rapist Danny Masterson, 47, shared a series of photos on her Instagram Stories on Sunday night, where she was seen having a good time with Kimberly Stewart, the 44-year-old daughter of famous rocker Rod.

Bijou, who shares nine-year-old daughter Fianna with Masterson and is the daughter of Mamas And Papas frontman John Phillips, walked the red carpet for the first time on Sunday after her estranged husband was convicted of raping two women in May and sentenced in September to serve 30 years to life in prison.

She and socialite Kimberly appeared to be in good spirits at the 5th Jam For Janie event at the Hollywood Palladium, with the pair posing up a storm under red lights and in the bathroom.

In one cheeky snap, mum-of-one Bijou proved she’s still got it as she showed off her toned backside which was visible through the sheer material of her dress, which also included a black plunging bodysuit to leave something to the imagination to leave.

Socialite Kimberly shared a similar photo on her Instagram Stories, showing Bijou walking up the stairs with her dress billowing behind her.

The 43-year-old actress and Kimberly also proved they knew their positions, with Bijou sharing a candid bathroom photo showing the friends in the reflection of a mirror.

A crouched Kimberly, wearing a dark furry coat, appeared to be applying lip product to her pout while Bijou looked sultry with her leather jacket casually slung over her shoulder and a drink in hand.

In another image posted by Bijou, the youngest daughter of John and third wife Genevieve Waite, she smiled at the camera with actor Luka Sabbat and Kimberly.

To the side of the photo, Anya Taylor-Joy and Malcolm McRae were chatting with a third person in the background.

Bijou also gave her more than 57,000 Instagram followers a little glimpse into the annual party, hosted by Aerosmith’s Steven Tyler, sharing an interior photo of the event on big screens showing Tracy Chapman’s surprise Grammy performance.

For her first solo red carpet appearance after leaving Scientology, Bijou styled her blonde curly locks in natural curls and finished her look with a pair of strappy heels and a red lip.

Around her neck hung a delicate gold chain with a small pendant.

Speak with E! News at the Janie’s Fund charity event on Sunday, the 43-year-old actress said: ‘I’m doing well.’

She added that she and Fianna, who turns 10 on February 14, made a “great little team.”

Following Masterson’s conviction last September, Bijou has been left to raise their child alone while her estranged husband serves his time.

Nearly two weeks after his sentence was handed down, she filed for divorce from the That 70s Show star in a California court.

The pair started dating in 2004 after meeting at a poker tournament in Las Vegas, and got engaged in 2009 before saying “I do” at a castle in Ireland in 2011.

Last week, DailyMail.com reported that Bijou found Masterson’s move to a maximum security prison “very triggering”, insiders said.

Sources say she is “taking forever to heal” and is “terrified” of celebrating their daughter’s birthday without him for the first time later this month.

The 47-year-old was transferred to Corcoran State Prison in Central California, where Charles Manson had been held for years, a move that has reportedly taken an “emotional toll” on Bijou.

An insider exclusively told DailyMail.com: ‘The move Danny has made to his new prison was very triggering for Bijou and brought back emotions from the past that she is still trying to deal with.

‘She has been able to go out and also go on holiday, which has been a relief from the stress of being able to live a somewhat normal life again, but it still hurts her inside that her life has been changed forever.’

The source continued, “It’s going to get better, but it’s also going to take forever to heal from this. She has had a very stressful life because she had to deal with this and what her father was accused of. It has been an emotional toll that has taken her to places of extreme stress and heartache. It will remain that way for a long time to come.’
