Hold up—is that Vince Spadea?! The retired former Top 20 American interviewed Ana Ivanovic at a Yonex event in New York City before the US Open. In a clip for Outside the Ball, he dived right into her favorite thing about Manhattan, shopping.

The Serb also revealed she's not opposed to starting her own fashion line one day (à la Serena and Venus Williams).She's unsure of the future hypothetical name, explaining that she doesn't want Spadea to steal her idea.

The 28-year-old is not wrong to want to keep her lips sealed. The 42-year-old Spadea is actually a tennis coach, rapper and fashion designer these days (he designed the gold hat he's wearing).

Given Ivanovic's style on and off the court, it's a safe bet assuming that anything she ever designs will be both stylish and classy.
