They again sent the rumor mill into overdrive after being spotted partying together at Los Angeles hot spot Warwick earlier this month (Jun16). They were also seen dining out earlier in the evening, causing many to wonder if this is showbiz’s hottest new romance.

“They’ve been on some dates and they are hooking up. Rita is very into him, and she’s telling everyone they have real chemistry,” an insider divulged to Britain’s Heat magazine.

However it might not just be romance on 25-year-old Rita’s mind. Friends say the British singer is keen to work with Justin, 22, on some new music, especially after the success of her single I Will Never Let You Down, written and produced by ex-Calvin when they were still an item.

“Rita knows this would be a big opportunity for her music," the insider continued. "They have similar vibes and she would love to collaborate. Justin and his manager, Scooter Braun, could really help her with her career."

Rita is yet to release a follow up to her hit 2012 debut album, Ora, though has been putting out new music, including a collaboration with Chris Brown. She recently parted ways with her label Roc Nation after a string of legal battles.

As for Justin, the source says the Canadian star can definitely see Rita’s appeal.

“Justin thinks Rita is a hot woman and wants to spend time her, but he likes the chase,” they revealed.
