Just a month after being accused of stalking ex-BF John Mayer, Jessica Simpson has turned her attention away from J.M and his acoustic guitar and set her sights on getting back together with ex-husband Nick Lachey. Jess has recently been blabbing that divorcing Nick was the ‘worst decision of her life.’ The ‘Blonde Ambition star has begun calling Nick multiple times a day. Nick Lachey is so fed with his ex-wife’s constant bugging that he has changed his phone number so that she can no longer contact him.

“She wants to be the girl that Nick fell in love with again,” a tattle tells OK!

“She’s been calling Nick all the time – at one point he had to change his telephone number. She now can’t contact him even if she wants to.”
