Photos of Richards with Locklear's estranged husband, Bon Jovi guitarist Richie Sambora, recently appeared in celebrity magazines. One photo showed Richards kissing Sambora.
"I wish Heather well," the 35-year-old actress is quoted in the magazine. "Unfortunately, our friendship had to dissolve and I'm sad about that. The last thing I would want to do is create a media frenzy like this, especially as I'm trying to get through a divorce."
Locklear, 44, filed for divorce from Sambora on Feb. 2, citing irreconcilable differences. The two have been separated since Dec. 26, according to the divorce filing.
Sambora, 46, is seeking joint custody of their 8-year-old daughter, Ava.
Richards filed for divorce from Sheen in March 2005 after three years of marriage. The couple seemed to have reconciled after the birth of their second daughter, Lola, last year, but in January, they filed legal papers asking a private arbitrator to handle their divorce.
"This is all hard. It's very painful," Richards says in People's May 15 issue. "The thing that's getting me through all of this is my daughters, just staying focused on them."
Last month, Sheen was ordered to stay at least 300 feet from his estranged wife and their daughters, 2-year-old Sam and 11-month-old Lola, except during supervised visits.
Richards alleged in court papers that Sheen pushed her, shoved her, and threatened her and her parents. The papers also include transcriptions of phone messages Richards said Sheen left in April 2005.
Sheen, 40, denied the allegations.
