Lady GaGa's lovers are intimidated by her bisexuality.

The 'Poker Face' singer admits she is attracted to both men and women and this has caused problems with her previous boyfriends.

She said: "The fact that I'm into women, they're all intimidated by it. It makes them uncomfortable. They're like, 'I don't need to have a threesome. I'm happy with just you.' "

However, Gaga insists she has never been in love with a woman and the only man she had serious feelings for was a heavy-metal drummer named Luke.

She said of the relationship: "I was his Sandy, and he was my Danny, and I just broke."

Although she has a new boyfriend, the blonde star says the most important thing in her life is her career.

She added to Rolling Stone magazine: "My music's not going to wake up tomorrow morning and tell me it doesn't love me anymore. So I'm content with my solitude. I'm OK with being alone. I choose to have someone in my life when I can."

The 23-year-old star is not the only female celebrity to admit to having relationships with both men and women.

Megan Fox - who is dating actor Brian Austin Green - recently confessed she is attracted to women.

The 23-year-old actress said: "I have no question in my mind about being bisexual. I think people are born bisexual and they make subconscious choices based on the pressures of society."

'Mean Girls' actress Lindsay Lohan enjoyed a tumultuous relationship with Dj Samantha Ronson, while Black Eyed Peas Star Fergie has enjoyed several lesbian trysts.
