Dad-to-be Dan tweeted a photo of himself and James enjoying a night out in Sin City, adding the caption: "Me and @JamesLockie86 last night! Loving Vegas #TOWIV."
Dan and James jetted out to the US on Monday (23 September) to film two one-hour specials that will kick off the new series of The Only Way Is Essex.
Aside from checking out the casinos, the pair have also been soaking up the sunshine in the desert, as evidenced by this poolside picture shared by Dan. We're not jealous at all...
Dan had been working out hard ahead of the trip to Vegas, sharing a few shots of himself shirtless in the gym after intense sessions, much to fans' delight!
We can't wait to see what's in store for Dan and James this season. As we all remember, last series Dan enjoyed a brief fling with co-star Lucy Mecklenburgh but called it off when he discovered his ex-girlfriend was pregnant with his child
James, meanwhile, appeared to have eyes for newly-single Sam Faiers, but she viewed him more as a friend so nothing came of it.
We wonder if there will be any holiday romances in Vegas? Looking at these pictures we definitely wouldn't be surprised if they attracted their fair share of female attention Stateside!
