Currently in Australia on her impressive Monster Ball tour, Lady Gaga – real name Stefani Germanotta – is reportedly concerned that her traditional, Catholic parents will disown her if she ever embarks on a serious relationship with a woman.

The 24-year-old “Telephone” singer has been quite open in the past about her attraction to both sexes, penning the number one hit song “Poker Face” about the topic. According to a source quoted by the UK press, Gaga has had plenty of casual encounters with ladies, but never a long-term relationship… and she doesn’t think her family would approve.

“Gaga is unsure whether she wants to be with a man or a woman,” a source told British magazine Look. “She’s scared that if she falls for a woman, her family will reject her, because ultimately, they want her to settle down with a man. For all Gaga’s success, her love life is a mess - and at the heart of the matter is the fact I think she’s scared of allowing herself to fall in love with another woman. Stef told me her grandma is heartbroken that she hasn’t settled down and got married yet.”  Gaga firmly believes in gay rights, insisting just last month that people are born with their sexuality intact, whether straight or gay.  “There are transsexual women and transgender women,” she said, “and suddenly it becomes poisonous and something else because there are some people in this world that believe being gay is a choice. It’s not a choice – we’re born this way.”

Lady Gaga’s tour ends tomorrow at the Rod Laver Arena in Melbourne, VIC.
