Word around social media today was that Colin Kaepernick got his fitness model girlfriend , Brittany Renner, pregnant.   Apparently she made the announcement on her Instagram page & then shortly later deleted the post and put up a pic of her boo instead.  As the news made its rounds, she took to Instagram again to address the rumor — and then he put up a post of his own (without specifically mentioning the gossip).  Check out what she had to say & some of her sexy pics — I need some fitness tips from her ASAP!
