AJ won a battle royal on April 22, 2013, to become the number one contender to Kaitlyn's WWE Divas Championship. Kaitlyn soon began a storyline where she received gifts from a secret admirer. On June 10, after setting up Langston to pose as the admirer, AJ revealed it to be a mind game, berated Kaitlyn and left her in tears. Six days later at Payback, AJ defeated Kaitlyn to capture her first Divas Championship. While she continued to mock Kaitlyn, they participated in the first ever in-ring contract signing for a Divas Championship bout. At Money in the Bank on July 14, AJ won their rematch but later in the show caused Ziggler to lose his own rematch for the World Heavyweight Championship. She hit his opponent, Alberto Del Rio, with her title belt to protect him from further head injury, prompting a disqualification. Angered by her unwanted action, Ziggler ended their relationship. She exacted revenge by costing him another match, then attacked him with Langston. On August 2, Langston was banned from attending her matches. However, AJ again retained the title from Kaitlyn, who was betrayed by Layla. Kaitlyn and Ziggler ultimately joined together to defeat AJ and Langston in a mixed tag team match at SummerSlam on August 18.
