Sean Lowe had more to celebrate on Monday night's Dancing with the Stars
than just a sexy, complimented rumba
with partner, Peta Murgatroyd.
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.
To cap off the gifts and company, Giudici was especially impressed with Lowe's acclaimed routine from earlier in the night.
"She loved it," Lowe said. "She thought it was the best dance that we've had all season. She's always so supportive, though. Even if it was terrible, she'd say it was great."
