The 31-year-old reality TV star attended Nickelodeon's 24th Annual Kids' Choice Awards at the Galen Center in California on Saturday night alongside siblings Kim, 30, 15-year-old Kendall and Kylie, 13.

Kourtney looked stunning at the prestigious ceremony which honours stars of popular culture, and even kept her cool when suffering a wardrobe malfunction beforehand.

The zipper on my dress broke as Kim and Kendall were zipping me up. I tried on three more dresses for my sisters and we picked this vintage number. Kim kept saying, You are so calm! If my zipper ripped I would be freaking out. Thats just how I do it. Lol (sic), explained Kourtney on her blog.

The celebrity looked radiant in a pink floor-length gown, which was vintage. She teamed the frock with Marni shoes.

Kourtney took to the stage to present an award at the ceremony alongside Kim, and she admits the pair were nervous that the tradition of sliming celebrities would catch them out like it did gorgeous supermodel Heidi Klum, who got covered in gunk.

Kim and I presented onstage and were terrified the whole time of being slimed! she laughed. (C) Cover Media
