Danielle Fishel and Lance Bass at the official book release party for 'Here's What We'll Say' by Reichen Lehmkuhl at The Abbey, West Hollywood, California - 23.10.06

Bass, who dated the American TV star from 1999 to 2000, revealed his sexual preference in 2006.

And Fishel admits she's put her plans to marry on hold since hearing the jarring news, because she can't stop questioning the sexuality of her suitors.

Fishel tells U.S. tabloid OK! "I don't assume anybody is straight anymore. I'm always like, 'Hmm, I wonder if he's gay?'"

Admitting the pair were never sexually intimate, she adds, "I was naive, 17, and a good girl... I wish he'd felt he could have been honest with me then."
