Jessica Simpson: From 'Newlyweds' To Newly Engaged

Jessica Simpson is no doubt celebrating her engagement to former NFL player Eric Johnson, which was announced over the weekend (and prompted her dad, Joe, to tweet his congrats to his superstar daughter). But the singer has had her share of love-life ups and downs, and her story certainly doesn't start with Johnson.

Jessica married fellow pop star Nick Lachey in October 2002. The pair documented their marriage on their hit MTV series, "Newlyweds: Nick and Jessica." But their sweet kisses turned sour when Simpson and Lachey split in 2005; in 2006, their divorce was finalized.

The same year his marriage formally ended, Lachey began dating Vanessa Minnillo. He proposed to the former MTV "TRL" host less than two weeks ago. For her part, Simpson became romantically linked in 2006 to yet another pop star: John Mayer.

The blond star famously dyed her locks brown when she began dating the "Your Body Is a Wonderland" singer. The pair had an on-again, off-again relationship that lasted nearly a year. The exes later made headlines when, as Simpson was promoting her VH1 show, "The Price of Beauty," Mayer called her "sexual napalm" in an interview. (Jess laughed it all off.)

Before she met ex-footballer Johnson, Simpson dated Dallas Cowboys star Tony Romo. The pair hooked up in late 2007 and carried on a very public romance until their split in July 2009. She discussed a potential breakup with Romo in an issue of Glamour that hit newsstands the month after they split.

"If this article comes out and we're not together, I'd still love him, and he'd still be a huge part of who I am today," Simpson said, adding that breakups feel like "a death in the family."

Simpson turned heads in spring 2010 when she was spotted with the Smashing Pumpkins' Billy Corgan, who worked on a song with her. Simpson never confirmed the two were dating, but their public appearances together left fans wondering if there was something romantic going on.

"To be able to sit with Billy [is a learning experience], and I always feel comfortable with him 'cause he is a close friend of mine," she told. "And I know he had my best interest at heart and it was great to be able to collaborate with him and to have him there in the studio."

After Corgan, Simpson began going public with Johnson, traveling the globe with the ex-football player and celebrating her birthday with him abroad. In that same Glamour article, Simpson commented on whether she'd marry again, saying, "It was hard to imagine I would ever walk down the aisle again [after I divorced Nick]."

Well, it seems that she could imagine it with Johnson.
