Rihanna doesn't dwell on the past. She's got the tattoos to prove it.

Along with the Grammy Awards Sunday comes the unfortunate reminder of last year's incident with Chris Brown on the eve of the music biz's biggest night.

But the "Russian Roulette" singer is focusing on the future. To that end, on Ellen today, Rihanna expounded on the latest of her "approximately 13" tattoos.

"It reads, 'Never a failure, always a lesson,'" the 21-year-old said. "Basically, it's OK to make a mistake, just don't make them twice." Words to live by!

Which, naturally, leads to questions about her current status in the land of love, where she has recently been linked to baseball star Matt Kemp.

"Are you dating anyone now?" inquired Ellen, never one to hold back.

"No, I'm single," replies Rihanna, echoing what she said yesterday.

"Really? What about the guy we keep seeing you with?" asked a surprised Ellen, referring to Kemp, who has been seen frequently with Rihanna.

To which Rihanna simply answers with a laugh. While we would love more info from her, at least she's smiling before the Grammys this year.
