There was no way Rihanna was going to let 4/20 pass by without voicing her support for the Smokers Holiday.

On Tuesday (April 20), the pop superstar posted several titillating photos on Instagram, one of which features her smoking a blunt with the caption "Just because it's 420." Other photos features the Bajan beauty sashaying around in sheer lingerie from the set of her new video for "Needed Me," which will premiere today at noon.

One NSFW photo, shows Rihanna in her see-through negligee revealing her bare breasts. Not that we are complaining. Another soft picture shows her holding a gun while staring out of a window.

"Needed Me" is the third single from Ri-Ri's latest album, Anti, which also spawned the hit single, "Work" featuring Drake, which entered is 9th week at No. 1 on the Billboard Hot 100 chart.

Filmmaker Harmony Korine (KidsGummo) directed "Needed Me," and if the visual match the sensual pictures, her Navy (aka "her fans") will be in for a treat.
