Legendary couple, Beyoncé and Jay Z are officially parents again for the second and third time. Yesterday evening, news broke that the Lemonade singer and her mogul hubby had welcomed their newest additions at a Los Angeles hospital on Monday, June 12th. A source told PEOPLE, “Bey and Jay are thrilled and have started sharing the news with their family and closest friends.”

The Destiny’s Child alum’s father Matthew Knowles also confirmed the arrival of the twins on Twitter just in time for Father’s Day with a photo of balloons and the caption. “They’re here! #beyonce #twins #jayz #happybirthday, love, granddad.”

Though there have been rumors swirling since the news broke about the sex of the Carter twins, nothing has been confirmed yet. We do know that the new babies will join their 5-year old big sister Blue Ivy who has been seen around town with her mom at everything from the Beauty and the Beast film premiere to the Grammy Awards.

Queen B announced her pregnancy on Instagram with a stunning photoshoot that bared her belly back in February, Under the beautiful image she wrote, “We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. – The Carters”

Though the twins have officially entered the world, we don’t expect the notoriously private couple to make any statements about the new babies anytime soon. The Carters’ rep has made no comment at this time.
