Beyonce shares rare photos of her twins Rumi and Sir

Beyoncé is giving the world a rare glimpse at her growing twins, Rumi and Sir.

On Wednesday, the Grammy winner, 39, took to Instagram to share a series of photos of herself enjoying some family time in Malibu.

Among the photos was a selfie with her and her eldest daughter, 9-year-old Blue Ivy, who is also a Grammy Award winner, and shots of the 3-year-old twins she shares with her husband, rapper Jay-Z, as they frolic along the shore.

In one photo, the singer's daughter Rumi is seen rocking two buns and a rainbow dress with her back to the camera as she walks toward the crashing waves.

Another snapshot shows Beyoncé reaching for her son Sir's hand. He has his back to the camera as well, but he is also wearing a bun, khaki shorts and a white shirt.

The twins are rarely featured on the singer's social media accounts -- aside from a few photos posted to her website every once in a while.

The artist also gave her fans a few fashion moments as well, sharing several outfits on Instagram.
