The reason for her stunning transformation? Her husband has taken control of nearly every aspect of her life! "Kanye has a vision and wants everything to line up with that," says a friend of the couple. "So he's given Kim rules that she always follows."

Below, a sneak peek at his nonnegotiable list of demands! Pick up the new issue of 'Life & Style' to read the rest:

RULE NO. 1: No Makeup at Home

The rapper's obsessed with more than just Kim's clothes. "He likes her to be natural and has demanded that she wear less makeup — unless she's going to a big event," a source says. "When she does go out, he insists she tone it down. He wants her to show their daughter, North, that natural is beautiful."

RULE NO. 2: Contact With Exes is Banned

Kanye ensures he and Kim hang out with whom he considers to be the right people, including Jay Z and Beyoncé, Anna Wintour and John Legend. But Kim's forbidden from seeing any exes, says the insider. "He basically controls who she goes out with."

RULE NO. 3: No More Spin-Offs!

Kanye's phasing Kim out of the reality genre. "He already laid down the law about what she can and can't do for work," says a friend. "He doesn't want her filming any of the spin-offs with Khloé and Kourtney!"
