"You smack that -ss how many times?" – Just one of many replies flying in last night as Chanel West Coast grabbed her bestie's backside for a little birthday action. The 32-year-old rapper and "Ridiculousness" star updated her Instagram on Thursday to shout out fellow rapper and bestie Porcelain Black, real name Alaina Marie Beaton.

Chanel, whose own birthday last month turned into a mess after the LAPD shut her party down – and she yelled at the cops – was determined to make Porcelain's one a hit. Check it out below.

Scroll for the photos. Chanel, herself in the news for returning to the "Ridiculousness" set and doing it in swanky Versace sweats, had kept up the designer vibe that's been all over her IG of late. The "Black Roses" rapper, whose photos came from a studio, had been photographed near a pricey Louis Vuitton purse, but this photo wasn't about the handbags.

Chanel's post opened with a super-cheeky and bootylicious shot as she and PB posed backs to the camera, with Chanel cheekily grabbing her girlfriend's rear while wearing white sweatpants, a knotted cropped t-shirt, and high-top sneakers.

Keep scrolling for more photos, including Chanel's Jessica Rabbit undies one. The LOL Cartel founder also seen partying with Porcelain and holding a cup while waving her arms around, closed her post with a bad b-tches shot as the two struck hard ladies poses near music decks.

It turns out, these two have been busy bees in the studio. Chanel told her 3.4 million followers:

"Happy Bday to this bad bitch @porcelainblack! You a REAL ONE! Luv ya girl! We got a new song on the way too so stay tuned????"

Chanel's followers, who will slam her and this year called the rapper's face both "puffy" and like it was "on steroids," had nothing but good vibes for this post. The comments section, seemingly, also proved way more focused on the butt slap than anything else.

"Big booty hoes!! Hump wit it!!" one fan wrote.

"I luv dey way Yu touch her-ass right," another cheekily added.

Backsides and cheekiness doesn't always go to plan on West Coast's IG, though. In August, the rapper's bikini photo was removed by Instagram. See her repost below.

In August, West Coast updated from a California lake for a four-in-a-row bikini booty shot with her girlfriends. The rapper was furious when a fan allegedly reported the shot, with Instagram then removing it. Chanel, proving she's a hard-hitter, reposted the shot, writing:

"LMFAO....REPOST because this post was removed for “bullying and harassment” can someone explain what in this photo is bullying or harassment? ? I legit have been bullied on Instagram for years and few posts I report about it got removed."
