The singer turned reality TV star admits she has to have sex before she gets up every morning.
Married to Stephen Belafonte, Mel 35, told OK! magazine: "We're the same age - there's only nine days between us so we're a pretty horny couple. We're young, we both like sex.
"I've always liked sex and I'm married to Stephen and I'm going to make the most of it. We've got a great marriage and if we're not happy about certain things then we talk about it in a very respectful way - we don't necessarily yell at each other. Relationships aren't easy, you have to work at them."
"I've got to have sex before I get out of bed, that's mandatory in my bedroom!"
