Rihanna Smokes Giant Blunts and Bong, Chris Brown Parties with Fan's Sexy White Thong [PHOTO/VIDEO]: Chrianna Enjoying the Wild 'Single' Life, Karrueche Tran Jealous?

Pop songstress Rihanna is currently enjoying the single life... and although Chris Brown supposedly rekindled a romantic relationship with ex-girlfriend Karrueche Tran, the "Fine China" crooner appears to be basking in his naughty "playboy" status, too! The 25-year-old "Diamonds" beauty smoked some GIANT blunts while hanging in Amsterdam over the weekend, posting viral photos on Instagram and captioning them #leaglizeit. Meanwhile, Breezy performed at a popular Anaheim, CA nightclub on Saturday evening (June 22) - and panties started flying! One fan hurled Brown her sexy white thong up onstage... and he didn't seem to mind the rather raunchy gesture at all. Check out the weed photos and entertaining panties-throwing clip below. Oh, Chrianna, you never fail to amuse us!

It's no secret that RiRi enjoys indulging in marijuana bliss every now and then... just check out these photos she posted on Instagram from her recent trip to Amsterdam:

badgalriri: "Where am I??? At Heauxm!!!!!"

badgalriri: "I'm just a girl... #Amsterdam."

badgalriri: "She makes that look so good!! ;) @jennnrosales #amsterdam #motherland."

Sexy, or just inappropriate?

Speaking of inappropriate...

While performing at Anaheim's popular Heat nightclub over the weekend, one eager fan decided to present Brown with a sexy gift... a silky white thong from her very own booty. Breezy happily accepts... wonder if Tran's jealous of her beau's overly-flirtatious ways?

Surly there's plent of more wild Chrianna behavior to come this summer.
