Grammy Awards 2018: Rihanna, Rita Ora and Ruby Rose attend after parties in New York

RIHANNA, Rita Ora and Ruby Rose were among the stars to kick on after the Grammys.

RIHANNA has turned heads at a Grammys after-party wearing a low-cut dress as she partied with her rumoured boyfriend.

The Wild Thoughts singer, 29, attended the VVVIP bash at 1 OAK in the Big Apple with Saudi businessman Hassan Jameel, whom she has been linked to since June.

The rumoured couple partied until about 3.45am and left the club separately, People reports.

Rihanna won a Grammy for Best Rap/Sung Performance for Loyalty, her collaboration with Kendrick Lamar off his Grammy-winning album Damn.

Meantime, Rita Ora flashed her cleavage in a plunging, Madonna-inspired outfit as she attended the same party as her ex-boyfriend Calvin Harris.

The RIP singer, 27, and Harris, 34, broked up in 2014 after a very public relationship and bitt breakup. At the time, Harris was said to have stopped Ora from performing I Will Never Let You Down - a song they co-wrote.

Last October, Ora told The Guardian the pair were on “good terms now”.

“It’s one of these things that… Well, for me it’s in the past. Whatever I say somehow turns into a headline and it becomes a story again,” she said, according to the Daily Mail.

Also in the Big Apple for the Grammys was Australian model Shanina Shaik, with her fiance, DJ Rukus. Shaik posed on the media wall outside Universal’s bash held at Spring Studios, also attened by New Rules singer Dua Lipa and rapper Eve.

In Los Angeles, Ruby Rose attended a Grammys viewing party.

The Pitch Perfect 3 star is still recovering from major back surgery and used a walking aid as she attended the star-studded bash, thrown by Aerosmith singer Steven Tyler.

“So, for the past few years (decade) I’ve been dealing with a spine issue,” Rose wrote on Instagram this month.

“I am now recovering from a back procedure, but I do need to stay active, so before I get seen with my cane and wheelchair in public, I’d rather put it out there that I’m fine and going to be fine.”
