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

鈥淚f you鈥檝e wondered why I鈥檝e been so absent on my social channels it鈥檚 because I have never been more sick! It was the most sick first trimester of all my children,鈥 she explained on Instagram. 鈥淏oomerangs 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.鈥

But Hudson returned to Instagram with a bang 鈥 or should we say a pop 鈥 on Friday to share a video of the moment she and Fujikawa found out they鈥檙e 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 鈥 we鈥檙e totally crying too.

Hudson explained to her followers that the pregnancy sickness has made it hard to 鈥減retend everything is amazing,鈥 but now that she鈥檚 finally feeling better, she鈥檚 ready to share the news with the world. 鈥淲e have been trying to keep this pregnancy under the radar for as long as possible but I鈥檓 a poppin now!鈥 she wrote. 鈥淎nd it鈥檚 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.鈥

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-fianc茅 Matt Bellamy (of the band Muse). In December, Hudson and Fujikawa celebrated their one-year anniversary. Congrats to the growing family!
