Vanessa Lachey is shaking things up on American Housewife.
The TV personality makes her debut on Tuesday's episode of the ABC sitcom as Angela's (Carly Hughes) girlfriend of the week, Crissy, and only ET has the exclusive first look at her appearance.
A licensed psychologist, nobody -- and we mean nobody -- is safe from Crissy's analytical eye. Though she fancies herself as the one who sees through other people's facades, it turns out she has a lot to learn from Angela.
In ET's exclusive clip, Angela has Crissy dissect what's going on with Katie (Katy Mixon), who's fully expecting to meet James Van Der Beek. When she realizes it's an intervention staged by her friends... and Crissy revolving around her lying, things get a little hairy.
"Katie, please have a seat," Crissy (Lachey) asks before beginning her psychologist spiel. "Your lying is starting to cause a rift in your relationships and you need to start telling the truth."
"Maybe you need to start telling the truth," Katie fires back, putting on her psychologist hat.
"You're not licensed to do that," Crissy replies, prompting Katie to dejectedly accept her professional advice. When Crissy asks Katie to reveal specific lies she's told her friends, Katie doesn't hold back.
"Doris, remember you gave me money to bet on red when I went to Foxwoods? I lied. You didn't lose. I spent the money on a giant daiquiri," Katie says.
And when Doris (Ali Wong) feigned shock over Katie's huge revelation, Crissy reminds her not to react impulsively. Watch the clip above to see what happens next.
