Locklear's string of primetime successes comes to an end. After losing five million viewers from the first to second episode, her new NBC drama, LAX, in which she plays an airport exec, is axed by the network two months into its first season.
Locklear files for divorce from Sambora after reportedly intercepting an email to Sambora from a mutual female acquaintance that contained provocative pictures. "Richie's saying that nothing ever happened," a friend tells PEOPLE. Another says the split is a result of "issues that they've been trying to solve for years." Regardless of the cause, the pair remains dedicated to making things as easy as possible for Ava. In March, Sambora asks for joint custody.
Hanging out with David Spade at an afterparty for his Showbiz Show, Locklear is spotted smooching the actor/comedian at Jones restaurant and bar in West Hollywood. While the pair is seen out on the town cuddling, holding hands and kissing over the next few months, pals of Locklear say that the relationship remains far from serious. By September, the duo decides to take a break. "Heather is still going through a lot," a source tells PEOPLE. "It's just too soon for her to get serious."
After consoling Denise Richards when her marriage to Charlie Sheen fizzled, Locklear is hurt to find that Richards is now dating Sambora. Richards and Sambora both claim that their relationship was platonic until well after Locklear filed for divorce. "I wish Heather well," Richards tells PEOPLE. "Unfortunately our friendship had to dissolve and I'm sad about that. The last thing I would do is create a media frenzy like this, especially as I'm trying to get through a divorce."
Locklear, 45, cuddles with former Melrose Place costar Jack Wagner, 47, at the Celebrity Classic golf tournament in Valencia, Calif. The pair were first spotted getting cozy in March, but friends said at the time that they were not dating. But a Locklear source now tells PEOPLE the actress "a really good place. It's great to see her with someone who appreciates her."
Locklear's publicist confirms to PEOPLE that the actress is seeking treatment for psychological issues at an Arizona facility. "Heather has been dealing with anxiety and depression," her rep tells PEOPLE. It was only in March that a man, who claimed to be a doctor worried that the actress was suicidal, called 911 about an incident at her house.
Locklear is arrested under suspicion of DUI in Santa Barbara. The actress, who is found to be "disoriented and impaired," undergoes drug and alcohol testing. In January, she pleads no contest to reckless driving and her DUI charge is dismissed. As part of the plea deal, Locklear's sentenced to three years' informal probation. In April 2010, she's arrested again and cited for misdemeanor hit-and-run after allegedly hitting a no-parking sign near her Ventura County home.
Locklear reprises her role as ad exec Amanda Woodward on the CW's Melrose Place. "Heather’s involvement in the show is something we’ve been working on for some time as we couldn’t imagine creating and producing this show without the iconic character’s inclusion," executive producers of the show say of Locklear's return.
Just before turning the big 5-0, Locklear accepts Wagner's proposal, her rep confirms to PEOPLE. "He's a great friend. He was there during a very important time in my life," the actress once told PEOPLE about Wagner, 51. "He's always had my back." But the pair doesn't make it to the altar, announcing they've ended their engagement in November.
