When Heather Locklear is bad, she's good. When she's evil, she's delicious.

You'll want a heaping helping of Heather in "He Loves Me" (Lifetime 9 tonight) because she's beyond evil -- she's bat crazy! And this movie is fun, fun, fun.

Locklear plays Laura, a successful Seattle real estate agent, married to a cardiologist and the mother of a six-year-old daughter. Yet when we meet her, she's carrying on an affair that's almost all consuming. She goes to a psychiatrist to learn to stop. As she struggles with her issue, she begins to believe her husband is having an affair, and she's desperate that he not leave. That desperation leads to all kinds of trouble.
