Sean Lowe and his fiance Catherine Giudici were playful on Instagram ahead of their upcoming televised wedding while Desiree Hartsock offered them wedding advice.

Lowe shared a comical image of himself wearing a bear head and captioned the photo, "beary sad." Giudici then uploaded a photo of herself standing next to her soon-to-be husband in his animal attire and wrote, "Don't worry, Mama bear is here."

The day before, Hartsock attended an event to raise money for The Breast Cancer Research Foundation, where she was asked if she had any advice for the couple and their special day.

"Just pretend the cameras aren't there," she told Wetpaint. "Just enjoy the moment because they are doing it live, and that makes it a little different, and you can't edit anything out. I just hope they can have the same moments that they'd have, regardless of TV or not."

The Bachelor season 17 stars announced on Good Morning America earlier this month that they will walk down the aisle on Jan. 26, 2013 -- and it will air live on television. Lowe and Giudici's nuptials will be the first Bachelor wedding to air live.

Hartsock reportedly always planned to have a summer wedding but ABC producers told her she will now have to wait until fall 2014 because of Lowe and Giudici's special day.

"She's very upset about not being able to get married in the summer like she's always dreamed, but she's willing to make the sacrifice because she would marry Chris tomorrow if she could," an insider told Life & Style. "She just wants to get married so bad, but still wants to be able to take advantage of having a TV wedding."

Hartsock, who was a bridal gown designer and stylist before she became this year's Bachelorette, allegedly feels it will be worth the wait. She plans to create her own wedding gown and believes a televised wedding would be an ideal way to promote her own designs.
