Rihanna had a lot to talk about on a taping of the ‘Ellen’ show, including saying she’s ‘single’ despite her reported relationship with baseball player Matt Kemp. “Really,” says Ellen, “What about that guy we keep seeing you with?” To which the Pop Princess replied with a giggle. Riri also reveals her 13th tattoo, which reads “Never a failure, always a lesson.” “Basically saying, it’s OK to make a mistakes just don’t make them twice,” she explains. “I read that you said you’re going to fall in love by 31 years old,” says Ellen. “Is that real?” “No, but I hope I am,” replies Riri. “31 is a decade away. I better be in love by then.” The interview airs this coming Monday.
