Hailey Bieber reveals her totally flat stomach in a crop top for mirror selfie just 2 months after giving birth to son

HAILEY Bieber has channelled her inner Kim Possible for an incredible new look.

The star embraced Halloween by dressing up like the cartoon teenage spy, complete with a red wig, black crop top and green camo trousers.

Exposing her midriff, Hailey flashed her taut tummy just two months after giving birth to her baby boy, Jack Blues.

While she has largely kept the tot out of the limelight, Hailey shared a glimpse of baby Jack in order to encourage fans to vote in the upcoming election.

Posing for the mirror as the theme song for the Disney series plays over the post, Hailey looked just like the iconic crimefighter as she pouted.

Hailey and husband Justin later joined friends for a Halloween party, with Justin keeping a low profile and dressed in a black shirt like Kim's best pal, Ron Stoppable.

Kim wasn't the only Halloween outfit Hailey embraced this year, previously recreating The Simple Life and becoming Nicole Ritchie.

Joining best friend Kendall Jenner, who transformed into Paris Hilton, the pair donned farm clothes in a nod to the legendary reality show, which saw the socialites spend time on a farm.

A TikTok made by Hailey sees her recreate one of Nicole's most notable moments where she threatened to 'beat the a**' of a farmhand.

Throughout The Simple Life, the pair played up their privileged and entitled lifestyle for the cameras, but Nicole broke character when a man called Jimmy referred to them as "Dumb and Dumber".

In a scene that Hailey is seen lip-syncing to for this Halloween, Nicole is heard snapping back: “James, I have respect for myself and this is my best friend so I have respect for her, and I am being dead f**king honest right now that if you call me dumb or her dumb one more time…”

As Jimmy awkwardly laughed, Nicole continued: “I don’t care how many steroids you take, how many egg yolks you drink, how many pushups you do, I’m being dead f**king serious, I will beat your f**king face in.

"You think I haven’t done it? I have done it before and I’ll do it again. I really don’t care, so watch your f**king mouth,”

Both Paris and Nicole approved of the look, sharing the TikTok to Instagram.

Paris labelled them "iconic" for the homage while Nicole said: "I am obsessed."
