Congratulations are in order for one of Hollywood's most low-key couples, Joaquin Phoenix and Rooney Mara!
While the pair keeps things low-key they are undeniably one of the most high-key adorable couples in Tinseltown!
The pair have recently welcomed their first child together, a boy named River.
Of course, the name is in tribute to Joaquin's late brother River, who died in 1993.
