The Bachelor star Sean Lowe and his fiance' Catherine Giudici went out on a hot date after he performed on Dancing With The Stars season 16 on Monday.

The couple went to the Los Angeles nightclub Sayers on April 1 and displayed major PDA when they kissed in front of everyone at the hotspot.

Earlier that night, Lowe danced to the 1970s hit YMCA with his dance partner Peta Murgatroyd on the live show. For their performance, The Bachelor 2013 star wore a construction worker outfit that included overalls and a hard hat.

For the outing with his wife-to-be, Lowe wore a chic gray wool blazer, Henley top, blue jeans and Converse sneakers. Guidici was sexy in a leopard print dress with a leather jacket and strappy heels.

A friend of Lowe's revealed in a recent interview that Lowe's future wife is very impressed with his dance skills.

"Catherine thought it was great; she was really proud of him and surprised to see how quickly he's progressed," the source told Hollywood Life. "It's not an easy dance to do so she knows how hard he worked to get there."

When Lowe first performed on DWTS, Giudici sat in the front row and cheered her fiancé on. She shared her excitement in social media after the show. The Bachelor winner posted a photo of them backstage at the show and posted it on Instagram.

"Me and my gorgeous fiancée @clmgiudici post dancing," she captioned the photo.

Lowe, a Texas insurance agent, proposed to Giudici, a Seattle resident, with a gorgeous Neil Lane sparkler in Thailand on the season finale of The Bachelor that aired on March 11.

After she accepted his proposal, Giuidici said, "Today is the best day of my life."
