Snubbed: ‘Bachelor’ Sean Lowe Didn’t Invite ‘DWTS’ Partner Peta Murgatroyd Because Fiance ‘Catherine Is Jealous'

Millions of fans have been invited to watch Bachelor star Sean Lowe and fiancee Catherine Giudici’s January TV wedding – but one of Lowe’s closest pals has been excluded from the entire celebration, RadarOnline.com has learned.

Peta Murgatroyd, Lowe’s former Dancing With the Stars partner, has revealed that she wasn’t invited to the upcoming nuptials – despite previously expressing her excitement about choreographing the pair’s first dance.

“I’m not invited to Sean and Catherine’s wedding,” Murgatroyd confessed to InTouch. “I’m disappointed about it.”

The reason behind the apparent snub? Sources told the publication that Giudici is “jealous” of the Australian-born beauty and not happy about the pro dancer’s close relationship with Lowe during the hit ABC competition show earlier this year.

“Catherine was very jealous of Peta. Sean and Peta were spending so much time together and Catherine felt like she had to compete for his affection,” an insider told the mag.

Regardless, Lowe and Giudici are set to tie the knot on Jan. 26, 2014 – and the ceremony will air live on ABC.

“I think it’s only natural to have it on TV seeing as how our relationship started,” Lowe told People.

“This will be a cool opportunity to share the most special day of our lives with all the people who have been invested in us along the way.”

The couple is still living separately in Dallas, but Lowe says, “We’re stronger than we’ve ever been. And not to sound too cliched, but I fall more in love with her every day.”

Giudici recently took to social networking site Instagram to document her Bachelorette party, ahead of her upcoming wedding.

The Bachelor season 17 winner, 27, recently embarked on a weekend-long trip to Miami with a select group of close girlfriends.

"I truly am in love, Friday. Heading to Miami and can't wait to continue the girly time fun!" Giudici tweeted before kicking off her bachelorette festivities.
