Lady GaGa insists she isn't trying to outdo the Pussycat Dolls.

The 'Poker Face' star is supporting the girl group on their tour of Australia and although her opening set has attracted a lot of attention, she denies trying to overshadow the main act.

She said: "I don't feel that way about the Pussycat Dolls. I love them very much and I'm very grateful to them for having me support them. They've taken me all over the world."

The 'Just Dance' star also revealed she is working on plans for her own headlining tour later in the year.

She added in an online webchat with Dolly magazine: "I will be back very soon doing a headlining tour. Probably towards of this year or very early next year."
