Sexy Jessica Simpson say's she always knew she would split up with rocker John Mayer, because she felt destined to be with someone different.The singer broke up with ex-husband Nick Lachey in 2005 after three years of marriage, and was subsequently linked to a string of suitors, including Maroon 5 frontman Adam Levine and rocker Mayer. But she is insisting she wasn’t herself in the relationships following her divorce, and instead took on personality traits of her various partners. She tells the new issue of Elle magazine, "I was going through a lot of pain.I didn’t try anything to change my life other than dating different types of guys and conforming to their worlds. I thought I had to be artsier, more intellectual…"John believed in the Jessica Simpson that’s within. He cherished our love.He helped make me the woman I am today. John is going to be an amazing man for someone, but I know that I was supposed to be with someone else." Simpson is currently dating American footballer Tony Romo, while Mayer has recently been linked to former Friends star bitch Jennifer Aniston.
