Mariah Carey gives Blac Chyna a lap dance on stage

LAS VEGAS, June 27 (UPI) -- A pregnant Blac Chyna posted a video to Instagram over the weekend of Mariah Carey hoisting her on stage for a little lap dance fun.

She gushed over Mariah Carey and how beautiful she looked on the show.

Mariah Carey brought Blac Chyna on stage during her #1 to Infinity residency concert in Las Vegas Saturday. The mom-to-be was over the moon excited.

Chyna, 28, sat on a bed with her eyes covered while Carey's handsome dancers wriggled over her to the 2008 hit Touch My Body, US magazine reported.

"You're so awesome, they don't know what to do," Carey said to Chyna, stroking her with a pink ostrich feather.

One of the male dancers jumped on to the bed, straddled Chyna, then literally ripped off his white tank top and began thrusting his hips in a provocative manner as Chyna laughed below.

John Legend had a similar experience earlier this month.

His wife, Chrissy Teigen was overcome with emotion June 18 when Legend was invited onstage by Mariah Carey during another of her concerts in Las Vegas.

Legend joined Carey during a performance of her hit song "Touch My Body" where she sat Legend down onto a fancy bed where he was then blindfolded and tickled with a pink feather.

Carey, who got engaged in January to Australian billionaire James Packer, performs all 18 of her number one hits during her Vegas show.

Chyna is engaged to Rob Kardashian.
