Sean Lowe's fiancé Catherine Giudici revealed a secret grudge for actor Jason Biggs on Twitter.

Giudici retweeted the American Pie's actor tweet he wrote during the airing of the season finale of The Bachelor Season 17 when Lowe proposed to her

Biggs tweeted on March 11 as he watched the finale, "Ok, pretty clear that he chooses Catherine. Kidding aside-six months, they're broken up. F--king joke. #TheBachelor #TierrasForeheadHole #LA."

Giudici retweeted his original tweet and added the caption:  "Not that I've been waiting to tweet this for 6 months or anything..."

J.P. Rosenbaum, who married Season 7 The Bachelorette star  Ashley Hebert, asked Giudici on Twitter, "is today the 6 month mark?

Giudici slyly replied': "of being announced, yeah. Little do they know, I took his tweet as a challenge. So joke is on Sean :)"

Lowe proposed to Giudici in Thailand in November, 2012, according to Reality Steve, but the proposal episode didn't air until March 11.

Sean Lowe Catherine Giudici Wedding Update: 'The Bachelor' Season 17 Stars Moved To Dallas Ahead 2014 Nuptials 

The couple moved to Lowe's hometown, Dallas, last month.

In July, she told Life & Style about her experience visiting Dallas and meeting his extended family and childhood friends.

"I loved it. His family and friends are to die for and I love them so much," she told Life & Style. "It was a very grounding experience for both of us and gave us a glimpse of what our life would actually be like there."

The couple rescheduled their televised wedding to 2014 because they were not ready to film yet another television show. They revealed in a previous interview they needed to take a break from filming another show after Lowe competed on Dancing With The Stars for eight weeks -- only a week after The Bachelor season 17 finale aired.
