While all the attention was (quite rightly) on the birthday girl, we couldn't help notice Chloe's gorgeous new eye-skimming fringe as she arrived at Sushi Samba in Sin City on Sunday night (29 September).
And we're not the only ones who love it, judging by the comments online! One fan told her, "Am loving the fringe- really suits you," while another reckoned her overall look was very Kim Kardashian-esque.
Chloe and Lauren – who looked beautiful in her pins-flaunting ensemble - were joined by Chloe's brother Charlie and fellow castmate Mario Falcone for the birthday celebrations.
The gang jetted into Las Vegas from the UK last week to film two episodes of the new series of TOWIE - and crafty Lauren used the time difference to her advantage!
Lauren tweeted over the weekend: "So its my birthday in the UK in under 2 hrs then again in Vegas in 10 hrs which means double celebrations which also means...double drunk!"
Lucky Lauren later told fans she'd been treated to a stash of birthday presents from Chloe in the morning.
Chloe tweeted: "Happy birthday to my starship and my best friend. @LaurenPope so much love, hope all your wishes come true always #pops #starship love u."
The tenth series of TOWIE begins on Sunday, 6 October on ITV2 with two special one-hour episodes from Vegas.
