"Appreciate all of the congrats messages from everyone!" the reality TV star subsequently tweeted, adding that she believes the pregnant Kate Middleton looks better than her with a baby bump.
"Princess Kate makes me look like a whale. I tell myself its because she's taller."
Haynes -- who was actually engaged to another man, Nick Grisham, when she first competed Big Brother in 2010 -- married Godwin, her former high-school sweetheart, in March 2012.
Haynes first appeared on the twelfth season of Big Brother and placed fourth after her male alliance members turned on her. Although she wasn't victorious, Haynes won the "America's Favorite Houseguest" viewer vote and therefore walked away with $25,000.
She then returned to the game for the franchise's fourteenth season as a coach to the newbie houseguests. However, fans voted her into the game, along with the other coaches, and she ended up getting evicted sooner than expected, finishing in seventh place.
