Nick Lachey partied the night away with his ex-wife’s personal assistant Cacee Cobb. While Jessica is thousands of miles away in Sydney with her sister Ashlee, her trusted PA was whispering into Nick’s ear and dancing provocatively with him in a Las Vegas nightclub. Lachey hired an ultra-exclusive VIP booth for a group of pals at Pure nightclub in Caesar’s Palace and splashed out on $1,800 bottles of Dom Perignon champagne and Grey Goose vodkas. But for much of the night, 32-year-old Lachey was seen whispering with Cobb in his booth. The pair laughed and giggled the night away before taking to the dance floor and dancing with each other.
