Khloé Kardashian is keeping up with a new generation of little Kardashians.

The Good American mogul, 39, enjoyed a day at the beach in a sweet selfie she shared Sunday with son Tatum, 21 months, daughter True, 6, and 7-year-old niece Dream.

‘The Best Crew!!!’ Khloé captioned the photo in which they all appeared to be wearing pajamas.

She shares Tatum and True with ex Tristan Thompson.

Khloé is also close with Dream, daughter of her brother Rob Kardashian and his ex Blac Chyna.

On an episode of The Kardashians last year, Khloé said she considers herself ‘like a third parent for Dream.’

Khloé also wished her kids’ nanny Andreza Cooper a happy birthday on Sunday with photos on her Instagram Story, including a poolside snap of the Kardashians star in a pink bikini with the birthday girl.

‘Happy birthday to my little cutie Sesha,’ wrote the mother-of-two.

She previously shared a video of herself playing with the kitten she got for True’s birthday last month.

A source previously told ET that Khloé is ‘in a good place‘ more than two years after she and Tristan, 33, split.

They called it quits when it was revealed that the NBA player had impregnated another woman around the time he and Khloé were expecting their son via surrogacy.

‘She isn’t focused on dating and doesn’t want any outside distractions right now,’ the insider said.

‘Family always comes first for her and she is happy with where she’s at in her life,’ added the source.

Ahead of her milestone 40th birthday next month, Khloé previously mused on this chapter of her life.

‘Growing up is really a crazy thing… when you’re younger, all you want to do is party, be out, be seen, be in the mix,’ she wrote in March while wishing twin pals Malika and Khadijah Haqq a happy 41st birthday.

‘You have tons of friends but none of them really know the real you,’ Khloé continued. ‘Then, you get a little older and with every year that passes, you crave more and more simplicity. More peace.’

Khloé wrote, ‘You crave friends that you can count on one hand. You crave doing the ‘nothingness’ with someone. The things that make you feel safe.’
