Looks like Nick Cannon can expect to have a very
happy Valentine's Day.
Wife Mariah Carey
shared this steamy shot on Instagram
Monday that proves once again that the mother of two
has definitely still got it.
"Working in my most favorite environment clearly having a bad hair day.. Haaaaaa," she captioned the shot, which a source tells PEOPLE was snapped in Puerto Rico.
Carey, 43, might be focused on her hair, but it's safe to assume most eyeballs zeroed in, um, elsewhere – namely on the serious skin she's showing while sporting a figure-hugging gold bikini top and matching sarong.
The former American Idol
judge has become quite the expert bikini strutter lately. In December, she posted a saucy snapshot
of herself during an Aspen family vacation, standing in front of a Christmas tree wearing a red bikini and matching robe.
She also posted a chilly-looking shot of herself walking her dog
in the very same bikini because, when you're Mariah Carey, why not?
