Barbra Streisand enjoyed a 70th birthday party to remember in Malibu, Calif., on Tuesday night, celebrating with close friends and enjoying a performance by her favorite singer, Johnny Mathis.
The legendary actress and singer was joined at Taverna Tony by about 80 guests, including John Travolta, Warren Beatty, Pierce Brosnan and Keely Smith, Steven Spielberg and Kate Capshaw, her stepson Josh Brolin and Diane Lane, Kenny G and Donna Karan.
The group dined on traditional Greek food, including hummus dip, Greek peasant salad, homemade veal sausages, chicken breast souvlaki and roast baby lamb.
"It was an intimate magical event with only very close friends, people I've known and loved more than 20 years," Streisand tells PEOPLE. "The highlight of the evening was my son's film that he made for me. People kept asking, 'Who is that singing?' And when I said it was Jason, everyone was blown away by the beauty and soulfulness of his voice. Quincy Jones wanted to sign him on the spot."
She added: "My friends made it an evening of surprises for me, flying in the remarkable Israeli mentalist Lior Suchard and gifting me with the performance of my favorite singer, Johnny Mathis, and many, many more highlights."
