The couple welcomed their first baby over the weekend in London.

Miller, 30, and Sturridge, 26, have been an item for just over a year.

Back in January, the stunning blonde actress broke the news of her pregnancy, and in February, she was spotted with an engagement ring.

Before giving birth, the twosome vacationed in Italy to prepare for their little bundle.

Let's hope they rested up!
