The couple of 16 years took to social media the day after an unretouched image of Crawford in lingerie went viral.

Marie Claire confirmed the shot originated from the December 2013 issue of their Mexico/Latin America magazine, and wrote "it is real, it is honest, and it is gorgeous."
Fans applauded the Photoshop-free picture of the former Cover Girl - who was 47 at the time - precisely for its realness.
20 years ago, Cindy was among the "Big Six": Linda Evangelista, Naomi Campbell, Kate Moss, Claudia Schiffer, and Christy Turlington - who famously quipped that they didn't "wake up for less than $10K a day" in a 1990 interview with Vogue.
The Midwestern beauty's memorable mole and ideal modelling measurements led to sexy Pepsi adverts, MTV's House of Style, and her disastrous acting debut in Fair Game with William Baldwin.
"I really think, at any age, it's learning to be comfortable in your own skin," Crawford told Marie Claire last week.
"If women would treat themselves with the same kind of love they give to their friends, that would be such a great gift we could give ourselves... What makes you the most attractive is self-confidence. That's what people see."
But even the 5ft9in stunner, who exercises four times a week, suffers through moments of self-doubt.
"I have those days," Crawford admitted.
"I don't want to act like I don't, especially now. As a young model, you have 4AM call times; now when they give me early call times I'm like, 'I'll get up whenever you want... but my face doesn't really like to get up before 7 or 8. I'll be there, I'm just not sure you're going to want to shoot me'."
Crawford and her husband are proud parents to son Presley, 15, and daughter Kaia, 13.
Truly her mother's mini-me, Kaia modeled in a Teen Vogue spread last November, and she scored a Young Versace campaign at age 10.
Crawford has fronted Omega luxury timepieces since 1995, and she just teamed up with Urban Remedy to launch an organic meal delivery service called Cindy's Essentials.
Meanwhile, Gerber - a former model himself - runs Casamigos Tequila with his longtime pal George Clooney and Mike Meldman.
