French Montana is raising his game -- at least when it comes to ping-pong.

At a party for the US Open in New York, the 33-year-old rapper challenged fashion designer Tommy Hilfiger to a friendly game of ping-pong. But French raised the stakes with a very expensive wager -- his diamond watch.

Hilfiger had reportedly been admiring the watch earlier in the evening, but the bling ultimately stayed on French’s wrist.

It was a close game. But in the end, French Montana was the party’s table tennis champ.
