Kristin and Nick: Summer of Love

and spent the last days of summer cuddling on the beach with friends in Malibu. The twosome arrived hand in hand at the Polaroid Beach House for the Playboy Energy Drink BBQ on Aug. 29 and wasted no time tasting the fresh grilled sea bass. Nick, 28, proved he had a romantic side and was doing everything for his girlfriend, “He took a pile of pillows down to the beach so Kristin, 19, had a place to sit.” The lovebirds laughed and had a great time with the 75 guests and Nick couldn’t keep his eyes off of Kristin. “They were so cute, inseparable really,” a partygoer tells OK!. “They even snuck off to watch the sunset together.”
