Meghan Trainor shares video of 4-month-old son seemingly saying 'I love you'

Meghan Trainor’s son is already talking -- sort of.

Meghan Trainor's 4-month-old son, Riley, is already talking -- sort of.

In a video clip posted to Instagram Monday in honor of the "All About That Bass" singer's husband Daryl Sabara's 29th birthday, the proud parents are seen repeating "I love you" to baby Riley. They pause and Riley replies with what almost sounds like an '"I love you" back.

Trainor, 27, and the "Spy Kids" alum scream excitedly and the proud mom says, "We're going to count it!"

Riley, startled by their reaction, almost starts crying before the video ends.

Meghan captioned the clip, "Happy birthday @darylsabara! You'll never know how much we love you."

The two welcomed Riley this past February, but Meghan later revealed the birth had its complications. Riley was breech and had to be delivered via C-Section, but he's healthy and happy these days.
