Despite the weekly presence of his fiancée, Catherine Giudici, sitting front-row in the Dancing With the Stars audience, Sean Lowe was still plagued by breakup rumors after his third successful week winning votes on the high-pressure dancing competition. "We couldn’t be happier," Sean told E! on Thursday night. "I'm so happy that we are finally in the same city having somewhat of a normal relationship. I couldn't be happier!" Meanwhile, his pro partner Peta Murgatroyd is working him extremely hard in rehearsals for tonight's Viennese Waltz. Last week, rumors ran wild in the tabloids about how Sean's brutal, time-consuming DWTS schedule was infuriating Catherine, who lamented her lack of time with him. But we have a sneaking suspicion that Sean will use this week's Best Year theme, in which the celebs open up about the best year of their lives, to declare the past year as his best—because he met, fell in love with, and proposed to Catherine during his season as The Bachelor . Plus, could tonight be a preview of what's to come at the wedding? Sean is dancing the elegant Viennese Waltz. And not too long ago, he said he signed up for DWTS so he could learn how to dance the waltz at his upcoming wedding. Speaking of the wedding, which Sean and Catherine promised would be filmed for an ABC special, Sean told E! that they still haven't made any concrete plans concerning the date, location, and other details. "Things are so crazy," he said this week. "We are going to let Dancing with the Stars settle down and then we will start mapping it out." Fair enough! KEEP READING ...
