Demi Lovato will mark the first anniversary of her rehab stint at baseball's World Series on Monday (24Oct11).
The singer/actress was admitted to rehab in October, 2010 following a breakdown on tour with the Jonas Brothers in South America.
Lovato is now in recovery and in the middle of a major comeback after revealing she struggled for years with eating disorders and emotional problems.
And, a year to the day after the beginning of her three-month rehab treatment, Lovato will perform the National Anthem at Game 5 of the World Series between the Texas Rangers and the St. Louis Cardinals on Monday.
The call-up to the big game comes just days after her sister Dallas tweeted that the Skyscraper singer should belt out the National Anthem during the Major League Baseball championship series, while watching Game 1.
