Kourtney Kardashian poses in pink lingerie and fishnets for Lemme photoshoot in the bath after son Rocky’s 1st birthday

KOURTNEY Kardashian looked incredible as she stripped down to pink lingerie for a sizzling new photoshoot.

The mum-of-four, 45, opted for a seriously glam shoot for her brand Lemme ahead of its latest product launch.

Kourtney looked sensational as she posed in the bathtub for the steamy pic which saw her expose her long legs in a pair of pink fishnet stockings.

Promoting her latest Lemme gummies to aid hair growth, Kourtney's luscious locks were spread out effortlessly over the side of the bathtub for the promotional image.

The Kardashians star opted for heavy make-up with a smoky eye as her extremely chiselled jawline was on full display in the striking photo.

Kourtney flashed a look at her surgically-enhanced chest in the daring pink underwear as her fans flocked to gush over her beauty in the sexy snaps.

One of her followers said: "Regal is the word that defines this photo."

Another added: "You look so beautiful."

Before a third commented: "Kourt looking so fabulous."

The steamy shoot comes just days after Kourtney celebrated the 1st birthday of her son Rocky Thirteen Barker who she shares with her husband, Blink-182 drummer Travis Barker.

45-year-old Kourtney - who shares three children with her ex Scott Disick - threw an elaborate party at the $35,000 Disneyland Club earlier this week.

A photo dump posted to Instagram this week saw Travis doting on their little one, whose face was hidden behind a red heart emoji.

She snapped some shots of balloons, a food stand, as well as a merry-go-round and Mickey Mouse himself.

They had even organised for a personalised 'Baby Barker' welcome sign to greet them upon their arrival.

The original invite-only establishment is located in Disneyland California, although can also be found in Disney World, Tokyo Disneyland and Shanghai Disneyland.

Founded by Walt Disney, it offers a speakeasy-style setting with luxurious amenities like fine dining, alcohol, and rare memorabilia.

Membership requires a hefty joining fee of up to $50,000 and annual dues of $35,000, with perks such as VIP tours and private events.
