Grammys 2019: Red carpet arrivals

Over. The. Top.

That's the expectation for this year's Grammy Awards fashion, and stars like Camila Cabello, Lady Gaga and Cardi B went above and beyond.

Lady Gaga made the biggest entrance of the night, posing like the diva she is as the paparazzi snapped away. She was even joined by Jennifer Lopez, which made for quite the photo op.

Meanwhile Alicia Keys, who is the Grammys' first female host in more than a decade, was a showstopper in a long-sleeved crimson gown with a plunging neckline.

See all the 2019 Grammy Awards red carpet arrivals:

Embracing Valentine's Day early were Camila Cabello, who arrived in a rouge gown with head-to-toe sparkle, and Kacey Musgraves also donned a blush tulle number.

But as much as we love a gorgeous color choice, you can't go wrong with black, as Alessia Cara proved with her trendy but sophisticated look.

More standout style moments came from Maren Morris, Ashlee Simpson and Meghan Trainor.
