Jessica Simpson is seemingly ready to drop a bombshell tell-all on ex-husband Nick Lachey.

According to Radar Online, the 44-year-old American singer and actress is extremely angry at her ex-husband Lachey, as he is bringing up the past. However, Simpson has warned she might share more about him if he does not “shut his yap.”

For the unversed, the 51-year-old American actor and singer-songwriter made headlines recently by saying their MTV show Newlyweds made him cry and suggested his relationship with Jessica was part of the problem.

Sources claimed that Jessica is upset, especially because she is now going through a hard breakup with her second husband, Eric Johnson, with whom she shares three kids, Maxwell, 13, Ace, 11, and Bridie, 6.

“Jessica doesn’t understand why Nick’s running his mouth off, since he’s always had this bug up his butt whenever she said a word about their time together,” the insiders stated.

“He was very bitchy when she referenced it in her memoir, even though she tried to keep it classy and respectful towards him,” they added.

It is pertinent to mention that Simpson and Lachey were famous because of their TV show, which ran from 2003 to 2005.

The show showed the good and bad parts of their young marriage but their relationship got worse and they ended up annulling their marriage in 2006.
