Colton Haynes has been engaged for just over a week, but hes already got kids on his mind.

The Teen Wolf and Scream Queens actor announced his engagement to Jeff Leatham in an Instagram post on March 13. Leatham, who is the Artistic Director of Pariss Four Seasons Hotel George V, popped the question on a beach in Los Cabos, Mexico, with a little help from Cher and some fireworks .

Though the men have yet to set a wedding date, Haynes is already thinking ahead about expanding their brood. When TMZ caught up with the star in Los Angeles March 17, he said that he and Leatham were planning on having children hopefully really soon, before quickly clarifying, not before we get married.

Haynes, whose Instagram bio now includes soon to be father, posted a photo of himself standing shirtless in a pool Monday with a cheeky, parenthood-referencing caption.
