On the Monday, Feb. 1, episode of ABC's hit reality TV dating competition series "The Bachelor," Ben Higgins whisks the 10 remaining girls away for a vacation in Mexico and sets up a group date which consists of a romantic Spanish lesson. But contestant Jubilee's jealous side comes through as she watches Higgins with the other ladies and she doesn't try to hide it.

The ladies and Higgins sit in a classroom with a professor who will teach them phrases like "I am falling in love with you," "I want to kiss you" and "I love you" in Spanish-but first he asks them to warm up their mouths by rolling their tongues.

"Like, who speaks Spanish better isn't really important to me," Higgins says in his on-camera interview. "It's kind of who gives the best effort, who has fun with it I think will stand out the most."

Higgins then stands on the side of the room and the ladies take turns telling him they love him in Spanish, but Jubilee is having a hard time watching him give his attention to the other ladies.

"I hate seeing Ben be around the other girls," Jubilee says in her on-camera interview. "You just spend so much time being jealous every time he takes another girl's hand, you know, fighting for a glance from him with nine other girls. I'm like, 'does he remember who I am?' Like, our one-on-one was so long ago."

When it's time for Higgins to test out his Spanish phrases on Jubilee, she gets up from her seat and says, "I just don't feel like this means anything 'cause he wants to kiss everybody."
