London, April 19 (Inditop.com) Singer Pink poked fun at the reports that she’s pregnant with her first child with husband Carey Hart by joking about having a “600 pound baby”.

Pink, real name Alecia Moore, sparked reports she was pregnant after she was snapped with a slight tummy bump, reports express.co.uk.

However, she has refused to confirm or deny the claims, but took to her Twitter.com blog and said, “Off to the gym. Lord knows when this 600 pound baby comes out that I’ve been growing for eight years, i better be strong and physically prepared!”

Pink reunited with motocross racer Hart last year after a year of estrangement. They married in 2006.
