PHOTOS: Best of Hollywood at the US Open

The US Open has over the years seen an increase in celebrity attendance. 

This year is no different.

Even as the week marked the start of the business end of the tournament, there was considerable increase in the number of celebs flocking to watch the big guns in action.

Rediff.com spotted at a few known names in the Flushing neighbourhood of the Queens borough of New York.

Model Kendall Jenner was there for the women's singles quarter-final. The reality TV star was there to support both as Venus and Serena Williams fought it out in the middle.

Gigi Hadid, Kendall's BFF, and Joe Jonas were also spotted.

Model Hadid and singer Jonas are one celebrity couple rumored to be on the fast track to marriage, with the latter contemplating popping the question this winter.

An engagement is on the cards around Christmas.

Kim Kardashian also graced the occasion.

The 34-year-old reality star was spotted experimenting with a Gothic look.

A pregnant Kardashian looked cool in casual chic brown top and white trousers.

Jelena Djokovic was also seen supporting hubby Novak.

The Serbian world No 1 certainly did not have it easy against Feliciano Lopez of Spain.

Former boxing champion Laila Ali was also there, supporting pals Serena and Venus as they battled it out for a semi-final berth.

Republican presidential candidate Donald Trump and his wife, Melania Knauss-Trump, were also in the stands for the showdown between the Williams sisters.
