The 34-year-old former Girls Aloud singer androgynously. said she is straight but likes "Poker Face" hitmaker for being an all rounder, reported Femalefirst.
"Probably a little bit on Gaga because she's an all rounder. She's very androgynous at times and I love that.
"I'd like to think that there were times when I would dress up as quite androgynously. Even in 'St Trinians', I loved dressing up as a boy," Sarah said.
The singer said she has had enough of dating men and although she is straight, she can appreciate a beautiful female.
