Jessica Biel

Rear view: Jessica Biel showed off her enviable figure – and J-Lo style posterior at the screening for film Easy Virtue in New York last night

Jessica Biel looked effortlessly glamorous in a body-hugging rhinestone studded gown when she took to the red carpet in New York last night.

But the dress wasn’t exactly what most people were focused on as the actress and girlfriend of singer Justin Timberlake’s Grecian-style Philip Lim dress gave a bootylicious view of her almost J-Lo-proportioned curvy behind.

The 25-year-old was at a special screening of Brit flick Easy Virtue yesterday supported by the Sexy Back singer.

He let her shine on the red carpet, but was there to hold her hand at the after-party at the Gramercy Park Hotel in New York.

While Jessica looked stunning in her A-list dress, Justin looked more like he was popping to the shops in a scruffy denim jacket, large black-framed glasses and an odd hat.

But their public appearance and ease with each other continued to dispel last month’s rumours that the couple were on the verge of splitting up.

The singer prompted speculation they were no longer together when he went to Kate Hudson’s 30th birthday party alone last week.

But a friend told Us Weekly: ‘Things are very good with them. They do things separately sometimes.’

The film will be launched on limited release in the US next week after it briefly showed in Britain last November.

Despite its short run, it was given rave reviews by Hollywood critics.

Getting into the holiday spirit, Jessica Biel teamed up with her family’s Make the Difference Network for a star-studded holiday party in Hollywood last night.

The “7th Heaven” hottie was joined by Kevin James in her hosting duties, and told press that it was a joy to team up with her family to help the Children’s Hospital Los Angeles this Christmas.
