Britney tells us she feels like an old person!

Britney Spears is having no fun at all. "I feel like an old person now," she says in Rolling Stone's next issue, out Friday. "I do! I go to bed at, like, 9:30 every night, and I don't go out or anything."

Her Album Circus is coming out on Dec. 2 - on her 27th birthday - with a live performance that day in New York City on Good Morning America. Her first single, "Womanizer," has been slowly climbing the charts, and Spears debuted the album's title track Tuesday on Elvis Duran's Z100 morning show in New York City. She is dedicated to work so very much that not even taking a break for Thanksgiving. The pop star boarded a plane Monday and headed to Europe to promote Circus overseas.

Britney shares her experience of her recent date that makes her wish she had just stayed home.  "Right when we got there, we just knew it was just bad," Spears tells Rolling Stone of one recent bad date. "He looked like an older version of Harry Potter, but skinnier. ... So I had to get dessert first. "And the other date I had, the guy was really, really tall and a lot older. ... We're trying to ask him questions, like, 'OK, you're into martial arts, so what kind of martial arts are you into?' And he was like, 'Oh, all kinds.' "No luck in love for Britney. Also those guys she dated did they not know it was Britney? I wonder.
