Actor Norman Reedus has gone public with his new girlfriend, model Cecilia Singley, after walking the red carpet together at an event in New York.

Rumours of the couple's fledgling romance have been swirling since April (13) and The Walking Dead star made it clear the 20 year old was his woman as they posed for photos hand-in-hand at the Z100 Jingle Ball concert on Friday (13Dec13).

Singley has since branded the images of the pair "cute", but while she admits a new relationship is developing in her life, she has declined to offer up any further comments about her new love when quizzed by editors at RadarOnline.com.

Reedus, 44, appears to have a penchant for models - he previously dated Helena Christensen from 1998 to 2003 and they have a 14-year-old son together, named Mingus Lucien Reedus.
