Celeb Spotter 074: Venice Film Festival and US Open kick off

As summer winds down, two star-studded events are taking us into fall.

Both the 2018 US Open and the 75th Venice Film Festival kicked off on Monday, with a slew of major names already being spotted at the events, both of which attract major, international crowds.

At the US Open, the likes of Hugh Jackman (with his wife), Anna Wintour and Gayle King have all been photographed taking in the action on Arthur Ashe Stadium during the tournament's famous night matches. Over in Italy, Naomi Watts, Ryan Gosling and Emma Stone have highlighted the first several days of the Venice Film Festival.

Also stepping out this week were Britney Spears and Lady Gaga, both of whom were spotted in Paris rocking outfits that were notable for very different reasons.
