Surprise! Kate Hudson revealed in an Instagram post today that she is pregnant with her third child — her first with boyfriend Danny Fujikawa.

“If you’ve wondered why I’ve been so absent on my social channels it’s because I have never been more sick! It was the most sick first trimester of all my children,” she explained on Instagram. “Boomerangs have made me nauseous, Superzoom is an easy way to have my head in the toilet, food Instagrams make me queasy, and thinking too much about Insta stories made me even more exhausted than I already had been.”

But Hudson returned to Instagram with a bang — or should we say a pop — on Friday to share a video of the moment she and Fujikawa found out they’re having a little girl. As they popped a series of big balloons, a flurry of smaller pink balloons revealed the exciting news as the couple and their friends and family screamed, cheered, and jumped up and down in joy. Yep — we’re totally crying too.

Hudson explained to her followers that the pregnancy sickness has made it hard to “pretend everything is amazing,” but now that she’s finally feeling better, she’s ready to share the news with the world. “We have been trying to keep this pregnancy under the radar for as long as possible but I’m a poppin now!” she wrote. “And it’s too darn challenging to hide, and frankly hiding is more exhausting then just coming out with it! My kids, Danny, myself, and the entire family are crazy excited! A little girl on the way.”

The new baby will join big brothers Ryder, 14, whom Hudson shares with ex-husband Chris Robinson, and, Bingham, 6, whom she shares with ex-fiancé Matt Bellamy (of the band Muse). In December, Hudson and Fujikawa celebrated their one-year anniversary. Congrats to the growing family!
