Ray J's pregnant wife has accused him of leaving her and their daughter "stranded" in Las Vegas after the BET Soul Train Awards.

The 38-year-old singer was accompanied to the BET Soul Train awards in Sin City by Princess Love and their 17-month-old daughter Melody on Sunday and couldn't resist showing off a family photo from the event on his Instagram account.

However, his spouse was unimpressed as she claimed things turned sour shortly after the event took place.

In the now-deleted post, Ray wrote: ""Thank you @bet #soulTrainAwards @princesslove @melodylovenorwood (sic)"

Princess then commented: "Left me and Melody stranded in Vegas and blocked me from calling.. now you wanna post family photos," she wrote with a laugh-crying emoji and the hashtag #ByeUgly. (sic)"

The 'Love & Hip Hop: Hollywood' star - who is eight months pregnant - went into more details on her own Instagram Story.

She wrote: "Yes I can fly home.. I have my own money. But my car is here and I don't want to drive back alone with my daughter because I'm over 8 months pregnant and I don't even want to have to stop for gas or go into labor with all of this human trafficking going on...(sic)"

Ray J has yet to address his wife's comment.

The couple announced in August that they were expecting their second child.

The "One Wish" hitmaker wrote on Instagram at the time: "Baby #2 on the way! @MelodyLoveNorwood your about to be a big sister! #Godisthegreatest @princesslove (sic)"

And Princess also used her own Instagram account to share the happy news.

She added in her own post: "Somebody's gonna be a big sis ... New addition arriving Jan 2020 @melodylovenorwood @rayj #2under2 #Blessed (sic)"
