Rihanna may not be ready to talk about her relationship with Chris Brown - she reportedly lashed out at the UK edition of Esquire when asked why her ex-boyfriend, who was convicted of felony assault against her in 2009, appeared on her "Birthday Cake" remix - but the producer of her next project fully condones her getting back together with the R&B singer, at least in the recording booth.

"I was happy to see it happen, to be honest with you," Sean Garrett told ABCNews.com. Garrett worked with Rihanna on her early single, "Pon de Replay," and co-wrote Brown's first hits, "Run It" and "Gimme That." "What was done was done, it was tragic," he said about Brown's 2009 assault on Rihanna, "but at the same time, I was just happy to see that they'd gotten past it and obviously she was cool with it."

"Cool" might be stretching it - in her interview with Esquire, Rihanna reportedly refused to talk about domestic violence and its impact on her, saying "I'm not here to [talk] about messy s**t."

Working and rocking risque fashion - or nothing at all, she posed topless for Esquire's July cover - seem to be her raison d'être right now. This month, she and Garrett head overseas to work on an undisclosed project that Garrett - who's made hits for the likes of Justin Bieber and Usher - promised would be "big." For those who question the 24-year-old pop star's judgment and health, given her decision to work with Brown, recent hospitalization, and penchant for clubbing, Garrett offered this: "She's a grown person, she's in control of her own life."
