Beyonce drops surprise new song with Blue Ivy taking centre stage

Beyonce has released a surprise new song and video — with her daughter Blue Ivy taking centre stage throughout.

The star did her classic trick of surprising fans by dropping the hit tonight, and this time her new song Formation shows a whole new side of the singer.

With explicit lyrics throughout, it flicks from dramatic Mardi Gras costumes to flood scenes and clips of Blue dancing with friends.

With a stream of tiny outfits, lingerie, and even a police car — Beyonce has already sent fans into meltdown — even giving Dr. Martin Luther King an appearance.

Showing off her winning dance moves, the star begins in a plunging red top and stockings, showing off major cleavage and her toned pins.

The song includes lyrics like: "I go hard… Get what's mine… I'm a star…'Cause I slay…I slay."

She adds: "Okay, okay, ladies, now let’s get in formation, cause I slay / Okay ladies, now let’s get in formation, cause I slay / Prove to me you got some coordination / Slay trick, or you get eliminated."

It's surely no coincidence she dropped the clip tonight- just a day before she performs at the Super Bowl 50 halftime show.

The new track is Bey's first since her Beyoncé: Platinum Edition was released in November 2014.

It's unclear if she'll perform the song during tomorrow's halftime show — but according to reports, she was spotted rehearsing it this week.

The cover art for the song sees Queen Bey with her head hanging out a car window, looking like a true goddess.

Formation is available on Jay Z's Tidal service.
