Nothing is going to rain on Barbra's birthday parade!
On Monday, Barbra Streisand celebrated her 75th birthday with some of Hollywood's A-list at hotspot Café Habana in Malibu, California.
The party lasted for four hours, and guests were served Casamigos tequila. An eyewitness tells ET, "Barbra stood and thanked everyone for coming. She also told stories for about 10 minutes and admitted to being a horrible public speaker."
