Rebecca Judd back on catwalk six weeks after giving birth to son Oscar

Rebecca Judd has made her return to the catwalk six weeks after giving birth.

The Australian model and Myer ambassador, who recently became a mother for the first time when she and her sports star husband Chris welcomed baby Oscar, showcased spring racewear at the VRC Spring Racing Fashion Lunch at Flemington yesterday.

According to the Herald Sun, Judd made four appearances at the fashion show alongside Dannii Minogue's partner Kris Smith, including opening the parade in an orange cropped jacked and dress by Arthur Galan.

Judd's mother Kerrie had reportedly flown over from Perth to look after Oscar while her daughter went back to work for the first time.

The model said that she was nervous about wearing heels on the catwalk, but put her post-pregnancy figure down to luck and "good genes".

Last month, Aussie supermodel Miranda Kerr made her return to the catwalk wearing a skimpy swimsuit only seven months after giving birth to Flynn, her son with actor husband Orlando Bloom.
