Billy Baldwin mercilessly MOCKS wife Chynna Phillips's 'luxury life' - before she shares video of herself FLIRTING with a 'very handsome' stranger while at a book signing WITH her husband

Billy Baldwin has mocked his wife, Chynna Phillips, for boasting about her lavish lifestyle as she prepared to reunite with Wendy and Carnie Wilson to bust out a tune at their close pal's book signing before gushing over a stranger's top-notch looks.

The musician, 56, who is the daughter of The Mamas & The Papas band members John and Michelle Phillips, took to YouTube to take fans behind-the-scenes as she attended Cass Elliot's daughter Owen Elliot-Kugell's book signing.

In the candid clip, Chynna - who recently lifted the lid on her struggle with drugs and alcohol - raved about her 'incredible' spa day before Billy, 61, cut her off and claimed that 'no one wants to hear about your life of luxury.' 

The video began with Chynna and Billy in the car discussing the massages they had recently.

The snide remark quickly got the songstress silent - with her spirits picking back up when she laid eyes on a mystery man who she dubbed 'very handsome'

They noted that they were left amused by their masseuse named 'Panda,' adding that she was 'the nicest lady.' 

'Panda's such a sweetheart and then the lady who gave me a massage was named Minnie and we're going back to that place, it was incredible. I mean they had me in a pretzel, she had her feet on my back, she was walking on me,' she said before her husband interrupted her. 

Billy quipped: 'No one wants to hear about your life of luxury.' 

The former singer quickly changed the topic as the duo headed to Owen's book signing. 

Once there, Chynna was filled with joy as she saw Owen autographing books. 

Chynna worked the room before spotting a 'handsome' stranger who she made sure to start up a chat with.

'You're very handsome,' she said to the mystery man.  He responded: 'Oh thank you very much, you're very beautiful.'

The former musician replied cheekily: 'Thank you, I know.' 

The snide remark quickly got the songstress silent - with her spirits picking back up when she had a special reunion with her former bandmates Carnie, 56, and Wendy, 54

The fun-filled night didn't end there as Chynna then reunited with Carnie and Wendy, who were apart of the Wilson Phillips singing group alongside Chynna (Wilson Phillips trip seen)

'Have you always been so confident?' the man fired back.

Outside, Chynna then joked to a friend: 'I'm still getting hit on, that's all that matters... I still got it.' 

During the book signing, Chynna also reunited with Carnie and Wendy, her bandmates from her singing group, Wilson Phillips. 

The talented trio took a moment to harmonize and congratulate Owen with a song. 

Carnie said: 'Owen, we love you so much.' 

'Owen, we love you. You did an amazing job,' Chynna added. 

Wendy said: 'You really shined tonight, baby.' 

Chynna then came up with the idea to start harmonizing. 

'Can we sing "We love you, Owen" in three-part harmony?" 

The group began singing with each other and then stopped to rehearse again.

Then, they sang: 'We love you, Owen, oh yes we do. We love you Owen, and we'll be true. When you're not with us, we're blue. Oh Owen, we love you.

'Born to sing together!'
