R&B star Ciara is set to show off her post-baby body next month (Feb15) by hitting the runway for a charity show during New York Fashion Week.

The new mum, who gave birth to son Future last May (14), has been flaunting her tight abs in 'selfies' online and on the red carpet after shedding over 60 pounds (27.2 kilograms) of baby weight, and now she will grace the catwalk as part of the annual Go Red For Women Red Dress Collection event.

She will strut her stuff alongside actress/singer Zendaya Coleman, Orange Is the New Black cast member Dascha Polanco, and veteran screen star Jane Seymour, who have all been added to the line-up, reports the New York Post.

Previously announced participants include Billy Joel's daughter Alexa Ray, reality Tv star Kristin Cavallari and Polanco's co-star Laverne Cox.

The American Heart Association fashion show, which raises awareness about women's heart health, will take place on 12 February (15).
