Barbra Streisand was left flustered by Kevin Costner because he was "so attractive."

Asked the last person to make her nervous, she said: "It was when I was interviewing Kevin Costner for the Prince of Tides', I was so nervous because I thought he was so attractive and I didn't know how to deal with it, I was the director.

"He could see I was nervous and said 'Let me give you a hug' and he made that go away."

Meanwhile, it was recently announced Bradley Cooper and Lady Gaga will star in a remake of Barbra's iconic movie 'A Star Is Born' and the veteran singer-and-actress thinks the movie will be "great".

She told 'Extra': "I feel great about it, I know Star is Born will work, it works every time. Because the music can change with the decades, so I know it's going to work."

The 'Funny Girl' star may have enjoyed decades of success, but she always had a back-up plan in mind.

Asked what she'd have done, she said: "I would have been a designer, an architect, something like that."

Barbra - who is about to release 'Encore: Movie Partners Sing Broadway', her 35th studio album and first LP for two years - recently admitted she only ever sings if she's getting paid.

She said: "I worry (about my voice) - I haven't sung in two years. Really, I haven't made a sound because I don't go around singing. There's no signing in the shower, no vocalising, no singing any time - unless I'm paid to sing!"

Barbra takes her most pleasure from her family, her husband James Brolin, 76, and her son, actor-and-director Jason Gould - her child with her ex-husband Elliott Gould.

She shared: "I'm pretty happy now, I have a good marriage. It's been 20 years since we met, time goes so fast. I'm very proud of my son. I feel very grateful."
