Bey and Jay have been completely silent about their new children, and haven't even officially confirmed the news she's given birth, but it was reported the twins were born on 14th June.
And it was reported they were being kept in hospital as a precaution after being born prematurely.
The boy and girl were said to be "under the lights" - a common treatment for jaundice, which sometimes occurs in premature babies.
According to TMZ the twins were born on June 14 in Los Angeles hospital and despite the "minor issue" the babies were expected to make a full recovery.

A source told the website: "We're told a "minor issue" surfaced, and as a result ... doctors do not feel comfortable releasing them. We do not know the nature of the issue.
"One source told us Beyonce also remains at the hospital, but as far as we know she's okay. The babies are expected to be okay as well.

"It's unclear when everyone will be released."
The Single Ladies star, 35, and her 47-year-old rapper husband Jay Z's twins now make the Carters a family of five alongside daughter Blue Ivy, 5.
“Bey and Jay are thrilled and have started sharing the news with their family and closest friends,” a source previously told People.
To accomodate the new arrivals, the famous couple are believed to be renting a sprawling $54.5million mansion complete with an infinity pool and separate house.
Known as La Villa Contenta, or the happy house, the Carter clan are thought to be settling in just fine and with the main mansion boasting 14 bathrooms, 10 bedrooms and a 25ft infinity pool - there is plenty of room to potter around.
Furnishings inside the main villa include a 'museum-quality' Chippendale mirror and 18th century chandeliers carved from amethyst and rock crystal and an unusual 2,500-year-old lion's head bust that was discovered at the base of Mount Vesuvius in Italy.
Relaxing walks can be partaken in the 6.3 acres of grounds including a rose garden with more than 1,000 flower bushes and a landscaped desert area.
