The Don't Wake Me Up singer has rekindled his relationship with the Diamond hitmaker, even though he is still on probation for brutally assaulting her in 2009 and friends of Chris say he is determined to make the relationship work this time.
A source told HollywoodLife.com, "He's curled up with Ri and he been with her this whole time this month and he's dedicated to her. He's trying to do the right thing with her and want to be right by her too.
"He's just trying to be a good man this year and so far he's doing that.
"Rihanna wants to spend everyday in January with him in 2013 because she thinks that will cement their relationship. She be on that whole sentimental stuff all the time."
Chris dumped Karrueche Tran in order to get back together with Rihanna and although he has been spotted sharing romantic dinners with her, friends insists he only has eyes for Rihanna.
The insider added, "Karrueche was always good to him and treated him like a king, but he's on Rihanna hard right now so I guess K.T. knows that and she's falling back."
