Lea Michele is throwing a 70th birthday party for Barbra Streisand.
The Glee star is a huge fan of the singer and actress and plans to pull out all the stops with a huge party as her idol reaches the landmark age on April 24.
A source told Hollywoodlife.com: "Lea is obsessed with Barbra Streisand.
"She has always celebrated Barbra's birthday, but this year is extra special because Barbra turns 70."
Lea, 26, will be joined at the party this weekend by her Glee co-star and boyfriend, Cory Monteith, and a host of their pals.
The source added: "Basically, Lea and Cory and her friends will watch their favorite Barbra Streisand movies and Lea will of course sing her songs."
Lea's obsession with Barbra doesn't end with her parties, as she also dreams of starring in a remake of one of her films, or having her appear on 'Glee'.
The friend said: "One of Lea's biggest dreams is to star in a remake of 'Funny Girl', which was Barbra's first movie role.
"In fact, one of Lea's other biggest dreams is to have Barbra actually be on Glee where the two could perform the song Evergreen together."
Lea met her idol once, in 2010, and subsequently broke down in tears because she was so shocked.
She recalled: "Someone tapped me on the shoulder and it was Barbra! She said, 'Thank you so much for introducing me to your generation.' I was like, 'Thank you so much. You've changed my life. I love you.'
"She walked away and I collapsed, crying like a crazy person."
