The party won't stop! Courtney Bingham Sixx continues celebrating milestone 30th birthday in hot pink bikini and sheer robe during spa day with pals

She reached the milestone age of 30 last week.

But the birthday fun has yet to end for Courtney Bingham Sixx, who continued ringing in the new age with a spa session at the Four Seasons Hotel in Westlake Village on Tuesday.

The third wife of Mötley Crüe bassist Nikki Sixx donned a hot pink bikini as she unwound with her pals at the luxurious destination, which is located nearly an hour north from Los Angeles.

Clad in a sheer floral robe that tied around her waistline with a bohemian leather belt, the rock star wife beamed as she posed beside an empty bath tub.

As usual, Courtney looked flawless with her highlighted hair blown out in soft and glossy waves, and her complexion dazzled with foundation and a healthy coat of mascara.

The beauty polished off the look with layers of gold necklaces, and a pair of beige heels that strapped around her ankles.

At one point, Courtney pulled her hair back to blow out the candles to her frosted white birthday cake, which was topped off with light pink rose buds.

The looker then indulged in the treat outside, in an area that was festively decorated with bouquets of white roses and custom-made towels that contained the monogram C6.

Not pictured in attendance was Courtney's rock star husband Nikki, who is currently on the final Mötley Crüe tour.

While the musician was unable to be present on Tuesday, he did lavish his other half with praise on Twitter the day of her actual birthday on Saturday. 

'HAPPY OFFICIAL BIRTHDAY TO MY BEST FREIND AND BEAUTIFUL SOUL @how2girl I LOVE YOU BABY,' he gushed, along with multiple heart emoticons. 

After three years of dating, Courtney married the former rock bad boy - who celebrated a decade of sobriety this year - at LA's famed Greystone Mansion last year.

Nikki's new wife is mostly recognized for her lifestyle blog How 2 Girl, which features Do It Yourself ideas for ladies on a budget via her website and iHeart radio program. 

Recently, the rock star discussed how he was keen to expand their family in an interview withThe Guardian.

The musician already has four children from previous relationships, including one with former Baywatch star Donna D'Errico and three with Playboy Playmate Brandi Brandt.

'I'm on my third marriage [to model Courtney Bingham] – my last marriage – and I want to have another child. I have four amazing children and it's been the greatest thing that's ever happened in my life.

'They teach me every day. I try to show them what I've learned. Gunner is 24, Storm is 21, Decker is 20 and Frankie is 14.'
