Beyonce's Dad Mathew Knowles Celebrates Arrival of Twins

Beyonce’s dad, Mathew Knowles, celebrated part of his Father’s Day congratulating his daughter and son-in-law on the arrival of their new twins.

“They're here! #beyonce #twins #jayz #happybirthday,” Knowles posted on Twitter and Instagram Sunday (June 18), along with a photo of balloons and a card that reads, “Happy Birthday to the twins! Love, Granddad.”

Beyonce and Jay Z welcomed twins earlier this week, according to multiple published reports. TMZ says that the twins -- reportedly a boy and a girl -- were born Monday in a Los Angeles hospital. Billboard has reached out to Beyonce’s rep for comment.

Rumors that the 35-year-old Lemonade singer was in labor began to captivate the Twittersphere after a "significant amount" of security was spotted at a hospital in L.A. Coupled with earlier reports that the couple spent $1 million to build a maternity ward in their Hollywood mansion, the news rapidly overtook the Internet.

The Carters first announced that they were expecting twins in February through a now-viral Instagram post, which pictured Bey flaunting her bare belly before a flower display.
