Linda Posada is not married, therefore she doesn't have a husband. She has dated several guys, but their identities are usually kept under wraps, due to Linda's profession.
She is a lingerie model, widely regarded as one of the most beautiful women in the world, who makes a lot of money being photographed without much in the way of clothes on, and the illusion that she is "available" to the men that view her photos is paramount to her success.
In Colombia, her native country, it is not unheard of for high profile models to conduct their relationships in secret in order not to put off male customers who buy into her image - but considering she was only born in 1991, it's also very likely that Linda Posada is still too young to commit to marriage just yet, which would explain why no marriage rumours have surfaced yet.
