The drama behind the scenes of Dancing With the Stars Season 16 grew this week, after the first star went home (voluntarily!) and gossip swirled around the most-watched couple of the season: Bachelor Sean Lowe and his fiancée, Catherine Giudici.

On Wednesday, Life & Style featured the couple on its cover, reporting that the engaged pair has been fighting constantly. And the source of the alleged fights? Sean's dedication to DWTS and his pro partner Peta Murgatroyd.

"The couple were caught having a major public fight at an LA hot spot—and again two nights later on the way back to their separate units in their apartment complex," reports the magazine. Apparently, the first fight took place at a DWTS after-party following Sean's first appearance on the show.

In a second fight, apparently two days later, Catherine called Sean "annoying," and appeared to be fed up with her dashing fiancé. Could rumors that Catherine is upset that Sean is spending more time with Peta in rehearsal than he is with her be true?

Peta made an attempt to put those rumors to rest in an interview with HollywoodLife, saying, "They are so in love, it's kind of sickening!" And Sean proved he's definitely spending quality time with Catherine by tweeting recently, "Watching @clmgiudici try on clothes. This is my life now."

In other couples news, Lisa Vanderpump's ridiculously handsome pro partner, Gleb Savchenko, may not be as available as fans would like to believe. According to an Australian outlet of Yahoo!, Gleb is married to another professional dancer named Elena Samodanova. Not that we were worried about Lisa's devotion to husband Ken (and Giggy).

As for adorable pair Aly Raisman and Mark Ballas, tonight's prom theme is making Aly all gaga over her cute pro partner. This week, she wrote in her blog, "Mark is really sweet and funny—definitely the perfect prom date!"
