The Bachelor's Sean Lowe took his fiance Catherine Giduci out for a romantic dinner for her 27th birthday at reality star Lisa Vanderpump's restaurant Villa Blanca on April 28.

Lowe tweeted his bride-to-be birthday wishes on Monday, the day of her actual birthday. He wrote on April 29, "Happy birthday to my beautiful and wonderful fiancée @clmgiudici !!!" .

Giduci tweeted her gratitude for her new life with Lowe in a simple message: "I am blessed."

Lowe's Dancing with the Stars partner, Peta Murgatroyd, also sent birthday wishes to the Bachelor winner on the social media site. She wrote on Monday night, "Happy Birthday gorgeous girl @clmgiudici May your day be filled with loads of laughter, joy and pressies xox See u tonight!"

Lowe and Murgatroyd performed a samba routine on DWTS  Monday.

Murgatroyd revealed some of the couple's wedding plans in late March. The professional dancer said she is teaching her partner how to waltz for his wedding day, and added that Guidici "has started planning" for the big day.

"We have talked about me working with them and choreographing the wedding waltz," Murgatroyd told Hollywood Life at an event on March 28. "They are totally down for that!"

DWTS host Tom Bergeron revealed on April 16 that the couple have set a wedding date for sometime in August of this year. He also confirmed that it will be televised.

Bergeron said during a DWTS episode, "My understanding is that the marriage ceremony of Sean and Catherine [Giudici] is scheduled to be broadcast on ABC in August," before he announced an elimination.

An insider said the couple have yet to decide where they will live after they get married. They are staying in LA until DWTS is over and will figure it out after that, a source told Hollywood Life.
