Nick and Vanessa are getting to know each other really well, really fast.

While Corinne revealed "the Corinne side of Corinne" on this week's episode of The Bachelor, it seems that next week, Nick is going to see a new side of Vanessa, whether he likes it or not.

Only ET has an exclusive first look at Monday's episode, where fan favorite Vanessa finally gets her first one-on-one date with Nick. The two experience zero gravity in an adventure-filled date, before the brunette beauty quickly falls ill -- and tries not to puke all over the Bachelor.

"I'm nauseous, and I'm scared that this is going to ruin the perfect first date, the perfect first moment," she says to the camera, in between clips of the pair falling through the air on a plane.

"This is horrifying. I'm not in control of my body. I'm mortified. 'Don't puke,'" she tells herself. "I want to get down on the ground, badly."

While Vanessa does her best to keep the barf bag at bay, it seems mind over matter just didn't work this time.

"I'm going to puke," she finally tells Nick, reaching for the bag.

While we'll have to wait to see if Nick and Vanessa can make it through their first date, Nick recently opened up to ET about another relationship landmark: saying "I love you."

"I'd be lying if I said I haven't gotten a little self-conscious about expressing an 'I love you,'" he admitted.
