We've been in denial up until now, but it looks like the final Backstreet Boy really IS off the market!!!
The twosome had a joint bachelor/bachelorette party in Las Vegas over the weekend at Palms Casino Resort!
The soon-to-be married pair began the raging weekend on Friday at Moon Nightclub with the Ciroc flowing and their love on FULL display with smooches and dancing.
But the party poppin' good time didn't stop there!
Let's just say, after watching him demolish that stuffed party favor blindfolded, Lauren will be one satisfied newlywed on their wedding night. HA!
Not to mention, the 7-carat rock Lauren showed off later in the night will happily weigh down her hand for the rest of time. *SIGH*
This Sin City party sounds so cute, it's sinful! LOLz!
With a couple this fun, we can't even BEGIN to imagine how AH-mazing their nuptials will be!
