Chris Brown is apparently trying to win Rihanna back.
"Chris called Rihanna to wish her a happy birthday," an insider tells The New York Daily News. "He's absolutely trying to get back into her good graces. He knows he's very much in the doghouse right now, and is doing everything he can to show her how sorry he is."
Brown sent the "Good Girl Gone Bad" singer a diamond bracelet and necklace as well as an iPod Touch. Brown's mom, Joyce sent over a bouquet of flowers, according to the Daily News.
The big question: Will Rihanna take Chris back?
"Rihanna so wanted Chris with her on her big day, but obviously realizes why they can't be together right now," the insider told the Daily News. "But it's becoming more and more clear that she can't be without him."
Rihanna celebrated her 21st birthday Friday with a casino-themed party in a rented house in the Hollywood Hills.
The Daily News says its source also told they that Rihanna is healing quickly from her injuries. "She hasn't scarred or anything," our insider reports. "She was in a great mood. She was really celebrating not just her birthday, but life in general."
Following the party, Rihanna hopped into a waiting car and jetted off to her native Barbados, where she finished out her birthday weekend with her mom.
