The 'Hold On, We're Going Home' rapper has reportedly told his beau he'll only make their relationship official if she agrees to cut all ties with the 24-year-old singer.
A source told the Daily Star newspaper: ''Rihanna and Drake are just having fun at the moment. Neither of them are relationship people really. But Drake has made it clear that if things are going to get serious with them, he doesn't want her speaking with Chris.
''They are never going to get along properly.''
Despite their turbulent past, Rihanna, 26, has never been able to stop complete contact with Chris, who left her bloodied and bruised when he physically assaulted her during an altercation in 2009.
Earlier this year, the former lovers, who dated on-and-off for three years, began texting each other more regularly.
However, Rihanna won't be seeing Chris for a little while as he is currently behind bars after he allegedly violated a judge's order by getting kicked out of the rehab facility in Malibu last week.
The 'Fine China' hitmaker was chucked out of the facility for allegedly breaking ''internal rules'' and, although it is not known what he done, it is not believed to be linked to violence or drugs.
Chris had been ordered to spend time in rehab for anger issues after an alleged assault in Washington D.C in October, which stemmed from his attack on Rihanna five years ago.
David Bowie and Rag'n'Bone Man both won two awards at the 2017 BRIT Awards at the O2 Arena in London last night.
