Lady GaGa vows to be 'bigger' than Madonna

Lady GaGa has vowed to be "bigger" than Madonna.

The 'Just Dance' star insists there is no limit to her ambition and will not to stop working until she is more successful than her idol.

She said: "I want to be around for 25 years. I admire Madonna and Courtney Love and the way they reinvent themselves and kick a*s. I want to do that and be even bigger."

The 22-year-old singer is prepared to sacrifice her love life to rule the charts - but admits she would find it hard to stay away from men.

She added: "I'm not interested in settling down. I just want to make music and f**k random people."

Lady GaGa has been touring with the Pussycat Dolls but has been disappointed by her performances. However, she has promised to show fans a better stage show when she returns in April.

She added to Britain's Daily Star newspaper: "I adore being in the UK but the shows I've done so far are nothing to what you will see from me.

"The dollar is so bad I haven't been able to take over all my equipment and do a full set - but I will.

"The US doesn't get me like you guys do but it doesn't bother me."
