Roberts took to Twitter to share pictures of the celebrations that took place across the weekend.
"Bye pals !! VEGAS bound with @kimberleyjwalsh & @lisalaudat1," she posted on Thursday (June 28), along with a picture of Walsh holding a cocktail in the first class cabin.
The girls' PR company then replied: "@NicolaRoberts @kimberleyjwalsh @lisalaudat1 Remember, what happens in Vegas stays in Vegas! Don't want phone ringing."

Roberts jokingly responded with "ring ring, ring ring", suggesting the weekend would be far from tame.
The 'Beat Of My Drum' singer then posted pictures of the bandmates downing tequila mixers together, with the caption "PATRON".
Cole, who turned 29 on Saturday, later shared a picture of a table decked out with balloons, surrounded by party-goers wearing masks of her face.
She tweeted: "Erm… few questions!! Who am I? Where am I?? Why am I?? What am I?"

According to the Daily Mail, the group enjoyed a dinner at the upmarket restaurant before heading to XS nightclub, where will.i.am played a DJ set and Cole joined him in the booth.
Fans of the singer also surprised her with a birthday gift, revealing on Twitter that they had raised over £2,800 for her charity The Cheryl Cole Foundation.
"Oh My God!!!!! You little Angels," Cole replied. "Thank you sooo much. That is the best birthday gift ever!"
Cole's latest album A Million Lights reached number two in the charts. The second single from the record, 'Under The Sun', is due for release this autumn.
