Denise RichardsDenise Richards‘ sister claims Denise hasn’t banned ex-husband Charlie Sheen’s parents from seeing their grandchildren - it’s that the grandparents aren’t interested.

Denise’s sister Michelle McLaughlin claims Martin and Janet Sheen are too busy to spend time with their granddaughters, two year old Sam and 11 month old Lola.

“I can count on one hand how many times they have chosen to see the girls,” she told Star magazine recently.

Meanwhile Denise’s new lover, Richie Sambora, is denying that he was unfaithful to wife Heather Locklear even though the pair only filed for divorce in March.

“I remained faithful during my marriage and I defy anyone to refute that,” he told Us magazine.
