Keeping Up With the Kardashians star Kourtney Kardashian stepped out with son Mason, nearly 7, on Tuesday (December 6).

Rocking her brother Rob Kardashian’s Arthur George socks, the reality star, 37, took her son to art class in Los Angeles, Calif.

On Monday, the proud auntie shared birthday greetings for her nephew Saint West.

“I can’t believe this was one year ago today. Happy birthday my little Sainty,” Kourtney Instagrammed the image holding her then-newborn nephew.

She also shared a sweet snapshot toting her nearly 2-year-old son Reign rocking a high ponytail.

The KUWTK star and her on-again-off-again beau Scott Disick – who are also parents to 4-year-old daughter Penelope – are back on again.

After a year-and-a-half apart, the famous exes, “are back together and giving their relationship a try again,” said a source.

I can’t believe this was one year ago today. Happy birthday my little Sainty.
