According to recent reports, Beyonce has given birth to twins, but the date of birth and gender of the babies are not yet publicly known.
Us Weekly, Entertainment Weekly and People magazines confirmed the news.
Beyonce announced her pregnancy in an Instagram photo in February – the most-liked post in history on the network.
The singer and her husband, Jay-Z, already have a daughter, Blue Ivy, aged 5.
There has been no official confirmation of the birth from Beyonce and Jay-Z themselves.
Other photos Beyonce posted after her pregnancy announcement showed her swimming under water, reclining on a bed of roses and sitting on a floral throne.
Speculation about the twins’ birth had grown in recent days after a woman was photographed entering a Los Angeles hospital on June 16 holding a card that read “B + J”.
Beyonce is the most-nominated star in the history of the Grammy awards, and her album Lemonade was the world’s best-selling record of 2016.
The singer had been due to headline the Coachella music festival in California in April, but pulled out on her doctor’s advice.
