Blac Chyna Shades Kylie Jenner, Sexy Bikini PHOTOS 'Turn On' Tyga? Thong Booty 'Revenge' & Disses Blue Hair With Fierce Red 'Do Makeover?

Kylie Jenner's going crazy on Instagram. First, the "Keeping Up With The Kardashians" teen debuted a funky blue hairdo on the popular social networking site:

And just a few days later, she posted a slew of sexy bikini pics from Coachella - probably her raciest bunch yet:

Woah. Oh - and now the 17-year-old beauty has pink tresses!

Maybe she's just trying to keep 24-year-old boyfriend Tyga on his toes?

But two can play that game - Blac Chyna still wants some viral cyber attention, too.

Following Jenner's racy "photo shoot," the former hip-hop video vixen flaunted her own makeover online. And she seemingly manages to shade Jenner with this sly caption:

blacchyna: "If u going to do it .... Do it right @kendrasboutique | Hair." 

So - which stunning Hollywood socialite now has the hotter 'do?

blacchyna: "I don't have to say much..." 

And Kim Kardashian's younger sis thinks she can rock a skimpy bikini? Well...

blacchyna: "#SweetPwussySatday."

Safe to say that some fans are probably LOVING this ongoing beef! Actually, several tweeters think Jenner needs to give things a break:

@EarthTo_Chrissy  53m53 minutes ago: "I don't know what's so 'inspirational' about Kylie Jenner she's more plastic than plastic cups and her bikini pants only cover her lower back."

@17Seniorss: "kylie jenner in a bikini. my mom would KILL me if i wore this..."

@zoelladuh: "how is Kylie jenner comfortable posting bikini pics like that on ig when her dad and all her family follow her."

@erikabowes: "If kylie Jenner posts one more photo in a bikini I'll die."

@Mandi_C_: "Why is Kylie Jenner wearing her bikini bottoms pulled all the way over her hips? 'The 80's called.They want their camel toe Mom style back.'"

Wonder if the "Rack City" emcee agrees?
