21-yr-old star crushes on married Kelly Ripa

There's nothing stopping Justin Bieber from expressing his deepest admiration for women... married or not, much older or not!

The 21-year-old singer admitted on Tuesday, July 14 that he has a big crush on model Kelly Ripa who isn't just a married woman but a mother of three children ranging 7 – 18.

Bieber posted an Instagram pic of the 44-year-old wearing nothing but a teeny bikini.

He captioned his post: "Wow Kelly makes me feel some type of way. No disrespect I know she's married! #bigcrush"

Ripa has been married to Mark Consuelos for close to 20 years, and they have three children together.Her oldest daughter, Lola Grace Consuelos is seven years younger than Bieber.

Meanwhile, Bieber is 23 years apart in age from Ripa. Ripa is actually old enough to be his mother. But then, when is age an issue?
