'iCarly' star Nathan Kress is expecting his first child with wife London: 'Our hearts are so full'

They grow up so fast!

Ex-Nickelodeon star Nathan Kress, who starred as Freddie on "iCarly," is about to be a dad! The 24-year-old and his wife, London, made the big announcement with one of the cleverest baby announcements in Hollywood history.

"Me and my baby in London. Me, and my baby in London. Me. And my baby IN --->LONDON <---," he captioned a photo of himself and London in London, England. "Get it??"

The two, who wed in 2015, look beyond smitten as they share a smooch along the River Thames. Another photo shows Nathan with his hand gently on London's belly -- although she couldn't help cracking a joke about the sweet moment: "I put my barf bag down for this photo," she wrote.

The littlest Kress is due in January 2018, and the parents-to-be are already preparing: "Our hearts are so full. Thank you guys so much for your support," Nathan tweeted. "Now to spend the next several months researching car seats & diaper cream!"

Nathan's "iCarly" co-stars Miranda Cosgrove, Jennette McCurdy and Jerry Trainor were all in attendance when he and London tied the knot nearly two years ago. In fact, they carpooled to the ceremony! "Riding together to see our baby boy @nathankress get married," Jennette wrote at the time.
