Justin Theroux partied with Orlando Bloom on Jennifer Aniston's birthday.

The 42-year-old actor and screenwriter enjoyed a boys' night out in New York City with 'The Lord of the Rings' star while his fiancée celebrated turning 45 in Los Angeles on Tuesday (11.02.14).

The 'Wanderlust' star and the British actor, who split from his supermodel wife of three years Miranda Kerr in October, wore matching black leather jackets and baseball caps as they attended an event for motorcycle club and clothing company Deth Killers of Bushwick before they proceeded to Jones Cafe in SoHo, according to UsMagazine.com.

Both stars, who are regularly spotted on motorcycles, were photographed performing stunts, including wheelies, on one of the brand's bikes.

Justin was forced to be apart from the former 'Friends' star on her special day, as he was busy filming his upcoming HBO series 'The Leftovers.'

But he was spotted shopping at West Village perfume boutique Aedes de Venustas earlier in the day, where he is believed to have purchased the actress a gift.

Meanwhile, Jennifer, who threw Justin a star-studded bash for his birthday at their $21 million home in Bel Air in August, celebrated her birthday with friends, including Courteney Cox, her hair stylist Chris McMillian and Tobey Maguire's jewellery designer wife Jennifer Meyer, at an intimate dinner at trendy L.A. eatery Soho House, according to E!
