It seemingly was a picture-perfect vacation.
“Great day with the girls and ended with seeing Mary Poppins!! The girls are loving NY!” Denise Richards Tweeted on Sunday during her trip with daughters Sam, 6, and Lola, 5, that included time with her ex, Charlie Sheen.
But by Tuesday morning, Sheen, 45, was sent to the hospital for treatment for what a police source says was suspected intoxication and Sheen’s rep called an allergic reaction to medication – and Richards faced a grilling by Howard Stern.
“Good morning!! Getting ready,” the actress, 39, Tweeted. “Heading to do Howard Stern this am!! Hmm what could he possibly ask this time?!?!”
