The 24-year-old singer is said to be rekindling her romance with Brown, reported Sun online "Chris's mum is Rihanna's biggest fan and is glad they are getting back together.
The pair get on really well. Joyce has also been urging him to cut ties with his ex, Karrueche Tran, to keep Rihanna happy," a source said. Brown and Karrueche attended a Halloween party together few days ago.
Rihanna is also hosting her own spooky event in LA and has reportedly invited Brown, who assaulted her in 2009, to be her date.
