They've reconciled enough to record a new track together, and now Chris Brown is wishing Rihanna a happy birthday by intimately using her birth name.
The 22-year-old singer - who was arrested for assaulting the Roc Me Out singer three years ago, tweeted to his now-amicable ex as she turned 24.
Rihanna retweeted the message from Brown, saying: 'Thanks! RT @chrisbrown: HAPPY BIRTHDAY ROBYN!'
She took the reconciliation to the next level by tweeting out a version of his single Turn Up The Music that features her own vocals in the background.
She wrote: 'Turn upt he music remix #RihannaNavy #Teambreezy enjoy!!!'
Though she doesn't seem shy about letting the world know she and Brown are on good terms, she did, after all, have something to promote.
The two have taken massive steps in recent weeks to becoming friends again.
Just one week ago, Chris snuck into her birthday party in Los Angeles.
