Beyonce shares candid photos with twins Rumi and Sir

Dec. 21 (UPI) -- Beyoncé is giving fans a candid glimpse into her life with twins Rumi and Sir.

The 37-year-old singer posted new pictures of Rumi and Sir, her 18-month-old daughter and son with husband Jay Z, on her website Thursday.

One photo, taken Dec. 9, shows Beyoncé smiling and holding Rumi as the toddler plays with a toy. The picture was taken during the singer's recent trip to South Asia.

Another snapshot shows Rumi and Sir sitting together on the shore of a beach. The siblings both wear diapers and sleeveless white shirts.

Beyoncé performed at a pre-wedding event for Isha Ambani and Anand Piramal in India this month, according to E! News. The singer took the stage Dec. 9 with her songs "Crazy in Love," "Perfect" and other hits.

Beyoncé is parent to Rumi, Sir and 6-year-old daughter Blue Ivy with Jay Z. She recalled the twins' difficult birth in the September issue of Vogue, saying Jay Z was a source of strength throughout the ordeal.

"My health and my babies' health were in danger, so I had an emergency C-section," the star shared.

"We spent many weeks in the NCIU," she said. "My husband was a soldier and such a strong support system for me. I am proud to have been a witness to his strength and evolution as a man, a best friend, and a father."

Beyoncé posted the new photos of Rumi and Sir the same day some of her music appeared to leak online. TMZ said old songs, including "Hey Goldmember," were posted to Apple Music and Spotify under the name "Queen Carter" before they were taken down.
