Rihanna, Chris Brown: Singer Tweets About 'Forgiveness' While On Set Of New Video

Rihanna spent Sunday on the set of her new music video, "Diamonds," for which she donned a sexy see-through gown.

But we have a feeling RiRi had something else on her mind during the shoot--namely her controversial ex, Chris Brown, with whom she was spotted Saturday night. Rihanna and Brown were caught on camera canoodling at a launch party for his Qubeey website at Playhouse nightclub in Beverly Hills.

While many fans are concerned about Rihanna's friendship with Brown -- who's still on probation for his 2009 assault on the "You Da One" songstress -- Rihanna invoked the Bible to make it clear she believes in second chances.

"Forgiveness wins," she tweeted, posting a verse from the Book of Matthew that reads, "For if you forgive people their trespasses, your heavenly Father will also forgive you."

Other recent tweets posted by the Barbadian singer include the observations "Temptation isn't sin," "If you start feeling like a "chore" to someone, you probably are!" and perhaps most cryptic (though likely a lyric from her upcoming album, "Apologetic"), "I found the one, he changed my life...But was it me that changed and he just happened to come at the right time?"

Radio host Elvis Duran, who knows both stars, weighed in on their relationship over the weekend, observing, "She seems to have forgiven him to a certain point, but you never know."
