Kate Winslet Officially Debuts New Dude on Red Carpet

Oscar winner is spotted at the San Sebastian Film Festival in Spain with Louis Dowler

Obviously feeling confident that her new relationship isn't going to sink like a certain luxury liner, Kate Winslet made a big public appearance on Monday with boyfriend Louis Dowler.

Complementing each other perfectly in their matching black attire, the couple was practically inseparable as they hung out at the Vanity Fair party at the San Sebastian Film Festival in Spain.

Sure, the Oscar winner and the Burberry model have been frequently spotted out and about since they began dating over the summer, but this is the first showbiz shindig the two have attended together.

And from the looks of it, the first of many.
