While co-hosting The Ultimatum's first season reunion episode, Vanessa said she had "mixed feelings" after learning that contestant April Marie went through now-ex boyfriend Jake Cunningham's phone without permission. But the 41-year-old former Total Request Live host then admitted: "I mean, I know there was a time in my life when I did it." Vanessa was, in fact, referencing a previous moment in her relationship with the former 98 Degrees crooner. Upon hearing the revelation, Nick, 48, appeared to be stunned. "You did it too," Vanessa said to Nick. "I'm actually surprised you figured out my password. That was a good one." Through couple's counseling, the longtime pair eventually realized they needed to learn to trust each other. "Honestly, I remember we went to a therapist and she was like, 'If y'all are going through each other's phones, then you shouldn't be together,'" Vanessa added. "I'm like, 'You're right. I need to trust this man and he needs to trust me.'" Nick and Vanessa Lachey on The Ultimatum.
