Justin Theroux is rumoured to have had his bachelor party in New York.

The actor-and-screenwriter could be getting married to Jennifer Aniston sooner than expected after it emerged he was at a stag party in the Big Apple last night (18.05.13).

One of his friends, writer Gavin McInnes, posted a photo of himself clowning around with Justin and another male pal on Instagram this morning.

He accompanied the snapshot with the hashtag ''#hunks'', before commenting on another photo of 'Double Date Dream Dolls' inflatable sex toys, cryptically writing, ''Bachelor party last night...''

Justin has spent the week in New York without his fiancée, who jetted back to Los Angeles after promoting her Living Proof haircare line in the city last weekend.

The 41-year-old star was spotted on the set of 'The Secret Life of Walter Mitty' visiting his friend Ben Stiller earlier this week, and at posh sushi eatery Nobu in TriBeCa on Friday night (17.05.13).

It is likely the bachelor party photos could be Justin's own since the couple - who fell for each other on the set of 'Wanderlust' - were thought to be planning a May wedding.

However, a recent report claimed they had decided to push their nuptials back to August to ensure their big day wouldn't clash with Brad Pitt and Angelina Jolie's plans.
