The former Bachelor star, 29, whisked away his fiancée, Catherine Giudici to a fancy dinner for her 27th birthday, immediately following the show.
“We had a big party with family and friends at Villa Blanca,” Lowe told PEOPLE on Tuesday of former fellow DWTS castmate Lisa Vanderpump’s trendy Beverly Hills eatery. “We had a good time celebrating. Peta was there and [pro dancer] Sharna [Burgess] was there.”
Gushed Murgatroyd of the big night out: “It was fantastic. It was a beautiful dinner. We all were merry and wished her many, many happy things.”
Even though Vanderpump joined the group at her restaurant, “I still had to pay for the food,” Lowe said with a laugh. “She did give us free appetizers and drinks. I’ll give her that. It would have been nice if she’d gotten my entrée. Come on, Lisa.”
But one treat for Giudici that was entirely at the expense of Lowe was “a nice purse, which Peta helped me pick out,” the hunky reality star said of the Louis Vuitton handbag he picked out as a gift.
