Mom-to-be Pink is just trying to stay on her feet.

In the latest set of amusing (and personal) Tweets that the singer, 31, has posted during her pregnancy, she admits she's having trouble walking.

"I am the clumsiest I have ever been in my life," she Tweeted Monday night. "Fell AGAIN today! I feel like my 92 yr old grammom … #dumb."

Explains the mama-to-be, "I just feel … silly. I fell up the stairs."

Less silly, however, is the Tweet where Pink explains what her mom went through when she was pregnant.

"My dad drug her by her coat 20 feet hanging from the car door in snow when I was in her tummy," she writes.
