Lopez and Khloe Kardashian joined the Fox show as presenters for the second season, but Landry has now admitted that she didn't want to see her former beau on television.
Speaking on Ryan Seacrest's KIIS-FM radio show, Landry joked that she had previously been a fan of the singing competition.
"I actually stopped watching [when he started]," she said. "I liked the show before he came on."
When Seacrest explained that he was going to ask if Landry thought Lopez had done a good job on the show, she replied: "I wouldn't know."
Landry and Lopez married in 2004 after six years of dating but Landry requested an annulment two weeks later when she discovered that her new husband had been unfaithful to her in the past.
Landry tied the knot with her second husband Alejandro Monteverde in 2006 and the couple - who were reportedly celibate before their wedding - have two children together. Meanwhile, Lopez recently wed his girlfriend Courtney Mazza.
