Charlie Sheen is reportedly very interested in what ex-wife Denise Richards is up to. So much so that he is willing to use Denise BFF Heather Locklear to try to spy on Denise.

Charlie Spying on Denise?

Of course Heather's loyalties lie with Denise.

Star Magazine gives this account:

Since Charlie and Denise are not speaking these days, friends say Charlie’s taken to calling their common friend Heather Locklear to gain insider info on his estranged wife.

“Charlie has called Heather several times in the past month, just nosing around to find out where Denise’s head is at, “friend of heather’s tells Star People”.

“But Heather says she refuses to get into it with Charlie other than to say Denise is OK” leaving Charlie quite perturbed, the source says.

Meanwhile, Denise was spotted out with former beau John Stamos at Malibu hot spot Nobu on what was called "a set up date."
