Chris Brown has been wooing Rihanna again, texting her.

“Chris started texting Rihanna on her birthday [Feb. 20], and the two have been sending each other a flurry of texts ever since,” said a source close to the singers, PAGESIX

“Rihanna didn’t write back right away . . . but later that night she started getting sentimental and texted back, ‘thank you,’ and asked how he was,” our source added. “Since then, the two haven’t stopped texting each other and friends are freaked out that she’s going to start dating him again.”

Brown infamously assaulted Rihanna in 2009, but the pair reportedly engaged in an on-again-off-again relationship when a restraining order against Brown expired in 2011.

RiRi celebrated her birthday last week in Aspen, then flew to Paris, where she was spotted partying at a nightclub with Drake. On Tuesday, she joined him onstage during his tour and performed her hit “Pour It Up.” The pair then performed their duet “Take Care.”

Drake and Brown got into a bottle-throwing bust-up at W.I.P. after Drake reportedly sent Brown a note saying, “I’m [bleeping] the love of your life,” referring to Rihanna.

RiRi says in the March Vogue, “I don’t go out of my way to be a rebel or to have that perception, but a lot of the decisions I make, a lot of the direction I want to move, is against the grain, or against society’s tight lane, and I’m aware of that . . . It might not be fitting with the norm, but that’s OK for me.”

Another source familiar with situation said it was Rihanna who initially reached out to Brown, to tell him she “missed him,” before she flew off to Paris to meet Drake on tour.

Reps for Rihanna and Drake didn’t get back to us. Brown’s rep commented: “[Chris] is focused about his recovery. He only wants the best for her and is happy that she found someone.”
