Did Jay Z just get served? Brooklyn Decker shared a video on Instagram on Monday, Jan. 27 of husband Andy Roddick impersonating Jay Z's acceptance speech at Sunday's Grammys -- and his acting could use a little work.

"This is what I make my husband do during award shows," model-actress Decker, 26, captioned the video.

"I'd like to say all the usual thank yous," retired tennis pro Roddick, 31, says into the camera in his best Jay Z voice. "Baby boo look, daddy got you a gold sippy cup . . . oh!"

In the 44-year-old rapper's acceptance speech on Jan. 26, he gave a special shout-out to daughter Blue, 2. "I want to tell Blue, 'Look, Daddy got a gold sippy cup for you!'" Jay Z said on stage at L.A.'s Staples Center as his famous wife Beyonce beamed from the audience's front row.
