Earlier this year, father-of-four Ryan heavily hinted that their youngest child's name could have an association with wife Blake's gal pal Taylor Swift.

During an appearance on the Today show, co-host Savannah Guthrie jokingly asked the actor: "Taylor Swift keeps dropping it into lyrics!", potentially referencing the singer's 'Betty' track from her Folklore album, which includes his older three kids' names.

Then, asked if the 34-year-old hit-maker gave any hints regarding his youngest's moniker in her latest album, The Tortured Poets Department, Ryan quipped in response: "We always wait for Taylor to tell us what the child's name is, and I'll say this: We're still waiting."
