Actress Bridgit Mendler (Born Bridgit Claire Mendler on December 18, 1992 in Washington, DC) has not made that aspect of her personal life public.
We can tell you of one study, though, that suggests that 87% of college students her age have had sex, so the odds are in favor of her having had sex by now.
Bridget's first professional acting role was in 2004 in The Legend of Buddha. She currently has 16 acting credits to her name, including such projects as General Hospital (2006), Alvin and the Chipmunks: The Squeakquel (2009), House M.D. (2012, and Good Luck Charlie (2010 - 2012).
There are only 2 episodes left in season 3 of Good Luck Charlie.
