Mamie, 35, is one of four children of Streep, 69, and her husband Don Gummer. The duo are also parents to Henry, Grace and Louisa.

US Weekly adds that Gummer and her fiancé Sethi, who is a producer, got engaged last August.

Both the iconic mother and daughter are busy making waves at HBO, with Gummer just finishing a run on \"True Detective\" opposite Oscar-winner Mahershala Ali.

Streep, meanwhile, is a highly-anticipated addition to the second season of \"Big Little Lies.\"
