Joan Collins has blasted fellow actress Kate Winslet, calling her hair "awful" and her sense of style "dreadful."

The 78-year-old Dynasty diva, who is famous for her glamorous looks, was shown a photo of the Titanic beauty at the Venice Film Festival and said, "Oh, that's a dreadful dress. The worst dress. And ghastly shoes and an awful hairstyle. I'm sorry."

But Kate wasn't the only target on Joan's radar -- she also blasted Gwyneth Paltrow for (half-jokingly) calling her grandmother a c**t during an interview, Carey Mulligan and singer Adele.

"I don't want to comment on Carey Mulligan. I can't believe she's playing Eliza Doolittle in a new movie," she told the Daily Telegraph.

"Adele is a very good singer, very, very talented, but she has a terrible hairpiece."

However, there is one star that Joan is a fan of -- former Spice Girls singer-turned-fashion designer, Victoria Beckham.

"Oh, I love Victoria Beckham," Joan said. "You've finally found someone I like."
