(Cover) - EN Showbiz - Ryan Phillippe and Amanda Seyfried were photographed leaving Kate Hudsons Halloween party together over the weekend.

The gorgeous Hollywood stars attended actress Kates annual star-studded party to celebrate the spooky holiday on Saturday night.

According to a photographer from the website TMZ, Amanda and Ryan were obviously a couple and did their best to avoid being pictured together to no avail. The photographer added Ryan was really sweet with pretty Amanda and claims the hunk had his hand around her as she chatted to pals.

As the movie stars got into a car together Ryan put the vehicles visor down to disguise his face and Amanda dressed in an enormous dog costume - attempted to hide her head behind the seat.

The pair are now being tipped as Hollywoods next big couple, and both have been in A-list relationships before. Ryan was previously married to Reese Witherspoon, and then dated Australian star Abbie Cornish until last February. Amanda reportedly split from her on/off boyfriend Dominic Cooper this summer. They had begun dating after starring in the 2008 blockbuster Mamma Mia!

Other stars at Kates exclusive bash included a mask-clad Leonardo DiCaprio and Nicole Richie sporting a fur coat. (C) Cover Media
