J.Lo Saves the Day! (Video)

Who knew Jennifer Lopez had such quick instincts? Must be the mama in her. Or maybe that dress! The superstar (and Grammy hero), who showed some serious leg in a daring black Anthony Vaccarello gown, came to Adele's rescue Sunday before Ukranian TV prankster Vitalii Seduik had his way with her.

The Grammy crasher, who snuck into L.A.'s Staples Center without a ticket or credentials, reportedly stole Adam Levine’s seat before walking on stage as Adele accepted her Grammy for Best Solo Pop Performance. J.Lo, being "from the block," must've recognized Seduik from prior pranks he pulled on Madonna and Will Smith and quickly shooed him away before he did any damage.

Adele later acknowledged J.Lo during her acceptance speech, calling her “my good luck charm!” Meanwhile, a source close to Seduik told The Hollywood Reporter the prankster spent the night in jail after being detained by event security backstage.

Check out the scene unfold below. We can't get enough of J.Lo's "What you think you're doing?!" glare:
