Serena Williams unveils clothing line at New York Fashion Week

World number one tennis star Serena Williams appeared to have recovered from her US Open woe when she unveiled her new clothing line at New York Fashion Week on Tuesday.

The 33-year-old missed out on claiming a calendar Grand Slam when she was knocked out by Roberta Vinci in the semi-finals at Flushing Meadows last week.

Away from the court, Williams proudly displayed her designs from the HSN Signature Statement Collection in a catwalk show in the Big Apple.

All eyes were on the front row as Williams's rumoured boyfriend Drake watched the show alongside Vogue's editor-in-chief Anna Wintour.
