Grammy Awards in Los Angeles amid a child custody dispute with her ex Rob Kardashian.

The 31-year-old reality star showed her upper thigh and ankle tattoos in the sparkling gown upon arrival at Staples Center.

She completed her outfit with red heels.

The mother-of-two accentuated her facial features with pink lipstick, eyeliner, thickened lashes and blush.

Chyna has a three-year-old daughter Dream Renée with ex-boyfriend Rob, 32.

She also has a seven-year-old son King Cairo with 30-year-old former fiance Tyga, real name Micheal Ray Stevenson.

Chyna and Rob have been locked in a court battle over custody of Dream.

Rob earlier this month filed court documents seeking a change in their custody agreement to obtain primary custody.

He accused Chyna in legal documents of abusing alcohol and drugs and of failing to take care of Dream’s personal hygiene, according to TMZ.

Chyna has denied his claims and called Rob a liar, with sources telling TMZ that she’s a good mother.

Rob’s sister Khloe Kardashian, 35, supported her brother’s peтιтion and filed court documents claiming Dream becomes more aggressive when being with Chyna, according to TMZ.

Khloe claimed that she noticed the change in behavior during play dates with her cousins.

Rob was seeking to alter Chyna’s custody time to just weekends with a nanny present.
