Accompanied by his male posse, the 31-year-old hitmaker was seen wearing a black baseball cap, grey T-shirt and black jeans as they arrived to the hotel with a whole lot of luggage.

The fact that the bachelor festivities are reportedly commencing would indicate that the Sexy Back singer's wedding to actress Jessica Biel will likely happen in the next few weeks.

Beforehand, the group - all dressed in retro suits - dined at Sinatra Restaurant in the Wynn hotel before going to the VIP section of the club just before midnight.

A source told OK! Magazine: 'Justin was all smiles but stayed hidden inside the private enclave.

'He was sipping on 901 Tequila throughout the evening but his posse were seen enjoying vodka and Red Bull shots all night.'

Over-the-top: There were model types all over the outdoor pool area of Surrender nightclub, but Justin was 'a good boy', according to one report

Weeks away? The couple of five years are rumoured to wed in the next few weeks at the five-star Yellowstone Club in Big Sky, Montana

Timberlake proposed to Jessica last December following a brief split; and although it was claimed they had tied the knot in a secret ceremony last month, the story was quickly denied.

And Jessica recently said she had done 'almost nothing' to prepare for the big day.

She said: 'I'm just enjoying being engaged. I do feel like there is a lot of time and nothing needs to be rushed.'

The on/off couple have been rumoured to be having their upcoming nuptials at the five-star Yellowstone Club in Big Sky, Montana later this year, but it might be happening sooner than anyone expects.

Justin and his Total Recall fiancée were last seen together while attending the after-party following the Los Angeles premiere of his new movie Trouble with the Curve on Wednesday night.

Earlier this month, Justin boasted about his bride-to-be and spoke at length about their home life, revealing they both love to cook.

Speaking to Jay Leno, he said: 'She’s really good (in the kitchen). It works out – she likes to cook, I like to bake, so dinner and dessert.'

The former Mickey Mouse Club member has been busy building his acting career and next year he'll star with Ben Affleck in Runner, Runner, and he'll appear in the Coen Brothers' Inside Llewyn Davis.

If you are committed to marrying someone you love, why the need to have a "bachelor party"? I mean, hasn't JT done enough catting around by now? It's more like a "I'll-be-right-at-the-altar-honey-right-after-I-tempt-myself-with a-room-full-of-willing-woman-with-plenty-of-alcohol-and-other-temptations-party!" IMO, if you're committed then show it. I've never understood this juvenile "bachelor party" thing. Like somehow it's a green light to have one last fling? I say this; "Grow Up!". That he's doing this only suggests what lies ahead. I give them 6 months.

Is Justin kiddin himself!? No way in a million years, is their relationship to this girl ever gonna work, given what's already happened between them in addition to their gustly hollywood way of commitment. She will use it against him in hard days. What happened to just staying the way they are to each other, rather than fetching more reasons to hurt each other even more. Keep it simple and UNCONDITIONAL

Jessica is beautiful but her beauty is dulled by that fringe (bangs). I hope she gets rid of the fringe before the wedding otherwise it will spoil the wedding photos forever !
