You've probably heard the expression the "Disney star curse," an epithet that people use to describe the number of former Disney stars who have had brushes with scandals, breakdowns and rehab stints. Now, yet another celeb has been added to this so-called cursed statistic-Zac Efron. That's right, the former High School Musical star apparently completed two stints of rehab treatment this year. Earlier reports speculated that Efron, 25, was struggling with alcohol addiction, but on Wednesday, TMZ broke the news that what he was really battling was an addiction to cocaine that started two years ago.

His second rehab stint came after a major relapse that he had in April while filming the upcoming Seth Rogen comedy Neighbors. Efron recently made appearances around the Toronto International Film Festival, looking happy and in a good place, so here's hoping that he has gotten back on the right track.

Another former Disney star, Miley Cyrus, also made headlines this week. But, come on, is that really all that surprising? Relatively fresh off her scandalous Video Music Awards performance that sent mothers across the country up in arms, the "We Can't Stop" singer, 20, is back in the news, this time for splitting with Aussie actor Liam Hemsworth. Reps for both Cyrus and Hemsworth, 23, confirmed to People magazine that their engagement has indeed been called off. 

The duo met while filming 2010's The Last Song, and after a rocky period of break ups and make ups, they got engaged in May 2012. News of their engagement ending surfaced just last Monday, but it didn't take long for additional reports to come out, stating that both Hemsworth and Cyrus have moved on. Last Tuesday, Los Angeles photographers captured Hemsworth in a passionate embrace with Eliza Gonzalez, 23, a Mexican actress. Miley has been linked to the 24-year-old producer of her new album Bangerz, Mike WiLL Made It-yes, that is his full professional name. Seeing as it took them no time to rebound, Miley and Liam have proven that they could-and did-stop.

In news not associated with former Disney Channel stars, Miami Heat player LeBron James married his high school sweetheart Savannah Brinson in California on Sept. 14. The wedding was a long time coming as James and Brinson got engaged in January 2012. The couple also has two young sons together. The four-time MVP ensured that their nuptials were kept private-wedding-goers could not have their phones for the ceremony or reception.

Last of all, just what you wanted ... an update on former reality television star Jon Gosselin! Gosselin, 36, who starred along with his ex-wife Kate and their eight children in the TLC reality series Jon and Kate Plus 8, made headlines this past week not once, but twice. For some reason, he became the talk of the town for taking a job as a waiter at a Beckersville, Penn. restaurant. Maybe this reemergence into the spotlight was just too much for Gosselin to handle because on Friday, he supposedly pulled a gun on a female photographer who had been following him home from the restaurant. TMZ claims that Gosselin confirmed to them that he fired off a warning shot to the photographer and he maintains that he had the legal right to do so.
