The couple rang in the new year while partying the night away with a group of friends at the MGM Grand Las Vegas hotel and casino, and shared a photo of their romantic New Year’s Eve kiss. “I am so ready to start the most defining decade of my life with @heatherraeyoung by my side!!” El Moussa wrote on Instagram. “We ended up in Las Vegas last night with a great group of friends and here is our Midnight pics!!❤️❤️” Tarek El Moussa/Instagram Young, 32, also shared the sweet snaps on her own social page, writing, “1-1-2020, Me + You, Love of my life ❤️Best Friend @therealtarekelmoussa.” Both posted a series of photos and videos from the festivities on their Instagram Story feeds, having a fun time as they welcomed in the new decade.
