Jessica Simpson has stepped out with her lips looking more plumped up than ever.

The country singer - who seems to be a big fan of collagen injections - was dining with friends at Da Silvano in New York yesterday evening.

And the Dukes Of Hazard star showed-off an exaggerated juicy pout, sparking rumours that she has had a little more help from the collagen fairy.

Jess - who is trying to establish herself as a country musician - attended Macy's 150th birthday cocktail party and was loving the attention from the paparazzi.

The singer literally had to be pulled away from the cameras after spending a long time and pouting up a storm.
