Things don't seem to be looking up any time soon for Kendra Wilkinson and Hank Baskett especially after a letter allegedly written by Baskett's rumored mistress, Ava Sabrina London, confirming the affair has surfaced.

According to Radar Online, though Wilkinson is still trying to stand by Baskett, the model rumored to be linked with Baskett has allegedly written an open letter encouraging Wilkinson to leave him. In the article published by The National Enquirer, which Radar Online has a copy of, London wanted to "clarify and validate the unfortunate facts" about the affair. London mentioned that Baskett had a "clear disregard" of the wedding vows exchanged between him and Wilkinson.

Furthermore, London told Wilkinson via the letter that she did not know Baskett was married at the time of their alleged affair in April, following to say that Wilkinson's children with Baskett, Hank Jr. and Alijah, are the victims. London even went as far as inviting Wilkinson to talk in person. In her letter, she also says, "My advice to you, whether you asked or not, is to divorce Hank and save yourself from any future heartache and pain." The letter also has her saying that Baskett will always be a cheater and that Wilkinson should save herself "from any future heartache and pain."

London's letter might just be the last push Wilkinson needed to finally file for a divorce, as Mail Online reports that in a preview for the next episode of "Kendra on Top," "the reality star goes on a foul mouth tirade at her husband." According to People, the preview, which can be accessed on the site, has Wilkinson talking about Baskett's affair, something that she "previously questioned" until then. Wilkinson's anger allegedly stems from something that her bestfriend, Jessica Hall, has forced her husband, Kyle Carson, to reveal about Baskett.

In response to Wilkinson's curses and threats, Baskett says, "You're going to believe this person over me and I have believed in you and supported you in everything."  

However, Wilkinson's mind seems to be made up. She was seen saying "it's divorce time!" and telling Baskett he is not wanted in the house.  

Before London's letter has been released to the public, audio tapes have been released again seeming to confirm Baskett's cheating with London. Wilkinson responded to these saying that they seemed like a setup, shares E! Online.  "It didn't make anything worse. It was just recycled crap," she said then.
