"Heather has phone records that prove Denise was calling Richie while Heather was still married to him," The New York Post quoted the source, as saying.

The source added: "Heather was such a good friend to Denise. She gave Denise clothes and offered her a shoulder to cry on when she and [now ex-husband] Charlie [Sheen] split up - there are even photos in the press of Heather taking Denise out after she and Charlie split. And then a few weeks later - not months - Denise starts dating Richie.

"For Denise to claim that not only did she not initiate contact with Richie but that she and Heather weren't friends for three months before she took up with him, well, that's just absurd and an outright lie. Denise also claims she's still friends with Richie - which is not true. He doesn't speak to her at all."

However, Locklear's rep did not comment on the issue.

Meanwhile, Denise's other claims on her show that she has five dogs, four cats and three pigs have also been slammed by many.

"Please - she has over 20 dogs, five cats, three pigs and several guinea pigs. Her place is like a zoo. She collects animals," said a source.

"I will not respond to these tireless rumors. It's such old news. I will say I have 10 dogs. Is there a law against having a lot of animals? My family loves animals, I live on a ranch, and I provide a great environment for them, so I am not sure why there is so much drama about how many animals I have," said Richards, via a rep.
