Roll out the royal red carpet! Prince George and Princess Charlotte officially have a new baby cousin following the birth of a second daughter for Lord Frederick Windsor and his wife, actress Sophie Winkleman, on Saturday, January 16.

“Lord and Lady Frederick Windsor have this morning announced the birth of their second daughter, Isabella Alexandra May Windsor,” a spokesperson for the couple tells Us Weekly. “The baby was safely delivered at 11:59 p.m. on 16th January 2016 at Chelsea & Westminster Hospital.”

The royal pair are already parents to daughter Maud Elizabeth Daphne Marina, 2, whom they welcomed in Los Angeles in August 2013.

Isabella will be the 43rd in line to the throne.

Lord Frederick’s father is Prince Michael of Kent, the first cousin of Queen Elizabeth II, making the royal family’s latest addition the queen’s first cousin, twice removed.

In a formal statement from the palace, it was noted that, “Her Majesty the Queen has been informed [of the birth]. Prince and Princess Michael of Kent’s family and Lady Frederick’s family are delighted with the news.”

Common-born Winkleman, 35, is best known in the U.K. for starring as Big Suze on the TV sitcom Peep Show. She and Lord Frederick, 36, tied the knot at Hampton Court in September 2009.
