“Lea is doing much better,” a source close to the Glee star tells PEOPLE.
The days and weeks since Monteith’s death in July from a lethal mix of heroin and alcohol were “”so for the actress, says the source, but Michele has found solace in her work both on the set of her Fox show and while shooting a video for her upcoming album over the weekend.
“A truly incredible day,” Michele Tweeted along with a photo from her video shoot on Sunday. “#dreamcometrue.”
And while Michele is feeling better, the source adds that she is not looking to date any time soon and is choosing to spend her time with close friends and diving hard in to her work.
“Happy Monday everyone,” Michele Tweeted Monday morning. “Early morning at #Glee today! Let’s get this week going!”
