Bitter much?

Just days after splitting from Little Mix singer Perrie Edwards, Zayn Malik majorly dissed his ex when he took a took a very public jab at his former flame and her group. But it looks like the British Rose is keeping her head held high! Our photogs snapped the the 22-year-old, who was smiling wide after winning big at last night's Teen Choice Awards.

On Sunday, The British heartthrob, who caused a stir when he left One Direction a few months ago, retweeted a Twitter message which asked followers to pick between rival girl groups' new singles -- aka "Retweet" if they wanted to vote for Fifth Harmony's new single or "Favorite" Little Mix's single.

Zayn took the opportunity to throw some serious shade at his ex lady love when he retweeted the status update -- which meant he voted for Fifth Harmony. Oh snap!

But Perrie didn't seem to let the jab get her down -- she looked on fleek when she attended the Teen Choice Awards last night and performed with her gang of gals. The ladies performed their number one single Black Magic, and also won the award for Choice Music Breakout Artist.

Perrie took to Instagram after her big win and gave some love to her bandmates , "I never thought my love for these girls could get any stronger... But everyday my love for them grows & grows! #SisterHood #Love Perrie <3."

Meanwhile, today Zayn got in a Twitter feud with Taylor Swift's boyfriend Calvin Harris after taking aim at T-Swizz for not being in Spotify. Calvin defended his woman when he tweeted, "You've made your money? Cool…f—k the 99% of musicians who depend on these services to survive right? Yeah F—k em.”

But Zayn wasn't about it take getting called out out lying down, so he wrote, “@CalvinHarris ha you just made an absolute fool of yourself mate. you clearly didn’t understand what I just said either…so I suggest you calm your knickers before them dentures fall out…Oh and I write my own s—t too d—knead."

Maybe someone should take away the former One Direction singer's Internet privileges?!
