Newly engaged couple Nick Lachey and Vanessa Minnillo are among an elite group of couples who have MTV to thank in part for their relationship. Former "Total Request Live" host Minnillo and former boy-bander Lachey appeared together on the channel long before they began dating in 2006.

Earlier that year, the pair began flirting on the set of Lachey's "What's Left of Me" video, which was also shot for an episode of "Making The Video." While they played a troubled couple in the clip, their chemistry on set was electric. "Nick is awesome," Vanessa said. "He's a gem. Mini crush."

Later, after Lachey finalized his divorce from pop princess and "Newlyweds" co-star Jessica Simpson, he and Minnillo went public as a couple.

They may never have gotten their own reality show like Lachey and Simpson, but the pair certainly never shied away from the MTV cameras, with Lachey making several appearances on "TRL" while Minnillo was still host. They even shared a kiss during the MTV's 2007 New Year's Eve special.

Minnillo and Lachey remained relatively public about their relationship, hitting up red carpets together in good times. But in the spring of 2009, the pair announced they had split, adding that they "remain good friends who still greatly care for one another."

After some time apart, they reconciled. That brings us to now when the pair announced their engagement. They got engaged on Thursday in California, and Lachey made the announcement on his Twitter.

"Hey all," he wrote. "If anyone's heard the rumors of my engagement, they are absolutely true! Vanessa and I couldn't be happier. Thanks for all the love."
