Exclusive: Jessica Simpson, Eric Johnson Are Engaged! PHOTOS: Stars dating athletes 
 
 Sources confirm to UsMagazine.com that the singer, 30, became engaged to beau Eric Johnson on Thursday, just days after Us broke the news that her ex-husband, Nick Lachey, popped the question to Vanessa Minnillo, his love of nearly five years. PHOTOS: Jessica's dress disasters 
 
 The Texas native began dating the former NFL player in May while he was estranged from his first wife, stylist Keri Johnson; their divorce was finalized five months later. Simpson and Lachey, 37, split in 2005, after three years of marriage. Simpson has since dated singer John Mayer and football star Tony Romo.On Saturday, Simpson was spotted wearing a large ruby and diamond ring on her left hand while making an appearance at a Kansas mall.
– If Nick Lachey can't put you off marriage, nothing will: Jessica Simpson, who divorced the ex-boy band star in 2005, is headed down the aisle again, this time with a former NFLer. No, not that one. Eric Johnson, former 49er and Simpson's beau of six months, popped the question Thursday—which, UsMag notes, is a mere few days after Lachey proposed to his longtime girlfriend, Vanessa Minnillo. Ah, the coincidence. Johnson "definitely makes me very happy," Simpson told USA Today. "He brings out a lot of light in me and makes me very comfortable being who I am. It's nice to be with somebody who praises you for the right reasons." But, sigh, first the holiday planning: "Having a boyfriend through the holidays, we're going to see how that all splits up," Simpson told Ryan Seacrest last week.
