Rumors have once again fueled that Rihanna and Drake are dating after the 'Diamonds' singer congratulated the rapper on the success of his new album via Instagram.

The Bajan beauty who once dated Drake when she called it quits with Chris Brown sent the Canadian rapper a sweet post on Monday.

"Congratulations @champagnepapi Excellent work!! #NWTS," Rihanna posted along with an image of Drake's Nothing Was The Same album cover.

The album, even after its leak did so well, selling 658,000 copies in its first week, which ended on Sunday, Sept. 29, according to Nielsen SoundScan. Justin Timberlake's The 20/20 Experience is the only album to sell more copies in a week this year when it peaked at No. 1 with 968,000 following its release in March.

NWTS debuted at No. 1 on the Billboard 200 albums chart with the second-largest sales week of 2013.

It's not the first time Rihanna gushed about Drake's work this year. In August when he released his single Hold On We're Going Home song, Rihanna tweeted lyrics from the song.

"Cuz you're a good girl and you know it!" she wrote before responding to a fan who continued the lyrics saying: "@_Vaun: I want your high love and emotion endlessly... RT @rihanna: I got my eyes on you..' My new fave record, period."

Enstars reported earlier that Drake and Rihanna were spotted on a romantic dinner date in New York City back in August during the 2013 MTV Video Music Awards weekend.

An eyewitness at the restaurant said Drake even kissed the Rihanna on the cheek.
