Jessica Biel seemed impressed with boyfriend Justin Timberlake's efforts as a runway model yesterday.

The singer took the catwalk wearing his self-designed threads at the William Rast show in at New York Fashion Week.

And the star had plenty of support in the front row, where Jessica Biel and his mom, Lynn Harless, clapped and cheered him on.

Justin gave a nod towards his mother and Jessica as he strutted his stuff alongside his design team.

Also admiring Justin's model moves was Paris and Nicky Hilton, who were also sitting in the front row.

And apparently Justin's debut fashion collection with William Rast even managed to wowed the attendent fashionistas.

The Big Apple went gaga for his new collection, featuring studded leather biker jackets and leather hot-pants.
