Fashion designer Stella McCartney welcomed a baby girl, Reiley, on Nov. 23, E! News reported Monday.

The baby was the 39-year-old McCartney’s fourth with her husband of seven years, British publisher Alasdhair Willis.

The couple’s other children are Miller, 5, Bailey, nearly 4, and Beckett, age 2.

The daughter of former Beatle Sir Paul McCartney — who launched her own fashion line in 2001 — is expected to take a short maternity leave.
