He became a big brother for the first time last weekend.

And Kendall Jenner is making sure that her adorable nephew Mason doesn't feel left out following the birth of Kourtney Kardashian and Scott Disick's second child, Penelope Scotland.

The 16-year-old model spent yesterday entertaining the two-year-old tot on the beach in Malibu, California.

Wearing a cute turquoise bikini and sunglasses, the reality TV star chased her nephew around on the sand as they played with a football.

Little Mason looked adorable in a pair of blue and white board shorts, and looked thrilled to have his aunt lavishing attention on him during their fun day out.

Kendall also seemed to be having a whale of a time as she chased the tot around, while showcasing her enviable washboard stomach and svelte figure.

After Kourtney gave birth to baby daughter Penelope Scotland last Sunday, Mason has found himself the centre of attention among his aunts.

Earlier in the week, Khloe Kardashian took the cute youngster out for a sweet treat at a frozen yoghurt shop in Calabasas, California, while Kourtney and Scott spent some time with their newborn.

And the 28-year-old star revealed Mason is adapting to his new role as big brother perfectly.

'And Mason is already loving being a big brother! This is just such a special and happy time for my family. Thank you to Kourt and Scott for making such beautiful babies! LOL. (sic)'

jealous much! so wish we had gorgeous beaches and matching weather here to chill out by the sea too. would make life that little bit more pleasant.

I think Kendall would suit being a VS model.

After watching keeping up with the kardashians I realised that this is the model family!! Don't judge a book by its cover

Who is this latest nobody?

shes to skinny even khloe is more attractive then her :)

That body is depressing!!!

do these people ever put down their mobile phones..............

she looks like she's lost weight..

I honestly think that young(er) people today are going to get permanently deformed hands from carrying their phones everywhere!!! Can you not even put it down when you are on the beach playing?

Kendall is undoubtedly a beautiful girl, but she is a little too skinny. Granted that she is naturally slender, but she needs to put n a little bit more weighty.
