Rihanna Bikini, Smoking Weed, Strip Club Instagram PHOTOS: Songstress Defies Pregnant Rumors: Parties 4/20 in Racy Gold Bikini Post-Miami 'Diamonds' Tour Gig

Is pop songstress Rihanna pregnant? From the sexy gold bikini, smoking weed, and wild strip club photos RiRi posted on Instagram over the weekend, it definitely doesn't look like she's flaunting any sort of baby bump! Following her sold-out "Diamonds" tour gig in Miami, the gorgeous Barbadian starlet kicked back poolside with a few cocktails and pals. Rocking a racy, cleavage-baring bikini, the "We Found Love" songstress definitely turned some heads on the web (especially after referring to one of her friend's toddlers as 'My lil' n#gga!'). She also posted several pics from her 4/20 celebration at the strip club. Check out the sexy photos below!

After falling ill and canceling several shows on her highly-anticipated "Diamonds" world tour, rumors started swirling that Rihanna was actually pregnant with Chris Brown's baby and merely experiencing "morning sickness." RiRi heatedly denied such rumors, and posted these racy, "bad girl" images on Instagram to prove her point:

badgalriri: "Shout out to my lover @charliebymz Thank u for designing what has to be my favorite bikini of all time!"

badgalriri: "#420 it's a celebration bitches!! Thank you to all my ft. Lauderdale and Miami fam that came through #DWT #backstageLife."

Oh, and she rode around on a bike flaunting just a white tee and g-string"

badgalriri: "What did I do to deserve the epicness that is my fans??!!! @janiseeaileen gyal you a real top shotta!!!!! Thank you for lighting up my day, no pun intended!! #420Life." 

badgalriri: "My lil nigga #clique." (Some fans were rather offended by RiRi's wording on this one).

badgalriri: "Playin hard to get, but he loves me!"

Typical Rihanna, keeping it real! Who approves of RiRi's sexy, hard-partying ways?
