Jessica Simpson has learned something from her past relationships with the likes of John Mayer, Nick Lachey, Tony Romo and (briefly) Billy Corgan.
"You can't love someone else to change them," the now-unattached Simpson Tweeted Sunday. "Happiness comes from accepting who they are," she continued. "It is our decision to REALLY know who we love."
The 29 year-old star's most talked-about former love is arguably Mayer, 32, who got in hot water last month for a blue-streaked interview with Playboy. In the infamous Q&A, he compared Simpson (whom he dumped in May of 2007 after a year together) to crack cocaine and said she was "crazy" in bed.
Did Mayer try to "change" Simpson? During their time together, the natural blonde went brunette, and "[Mayer] brought her to new places sexually, and they were dark places," an insider told Us. "She liked being a bad girl and being manhandled, but now she feels it was a mistake because of what he said in the interview."
Another Simpson source adds that the star is "disgusted" by Mayer's remarks. "He actually texted apologizing, like, 12 times, but she ignored it."
Simpson will appear on The Oprah Winfrey Show this Wednesday to promote The Price of Beauty, her new VH1 reality series which debuts March 15.
