Lady Gaga has laughed off rumours that she is pregnant, putting her changing shape down to getting older.

The Bad Romance singer told the crowd at her concert at the Hollywood Bowl that she did not have a little monster on the way and joked about the real reason she was ever so slightly heavier.

According to Mail Online she said: “I’m getting a little older and many people think I’m pregnant but I tell them, ‘I’m just almost f***ing 30!’.”

Gaga, who duetted alongside 88-year-old Tony Bennett, added: “Tony’s taught me you can live your life and feel the same every single day forever… Me on the other hand, I’m having a more difficult time with things.”

She grabbed her thigh and said: “A little more here and there.”

During the show, she also chatted about her fiance, Taylor Kinney: “I just tried to Skype with my fiance… He’s in Serbia. Every little bit I get with him, even though it’s not a lot, means so much.”
