It's a baby boy!

Confirming In Touch’s recent report, Jessica Simpson has officially announced that she's expecting a son! The pregnant star visited Jimmy Kimmel Live last night, where she accidentally let the cat out of the bag.

“The crazy thing is I never knew a wiener could make me nauseous,” the 32-year-old said about her morning sickness. “Well I guess I just told the world that I’m having a boy!”

Laughing, she followed up her big reveal by saying, “I can’t believe I just did that, that was not planned… I just did it so crude, I feel awful!”

The singer turned fashion designer and her boyfriend, Eric Johnson, will be giving their 10-month-old daughter Maxwell a brother this summer. As In Touch reported, sources close to the star say Jess wants to name her son “Ace or Acy” in honor of her maternal grandfather, Acy Edward Drew.

The 32-year-old later tweeted that her reveal was an "accidental announcement." Oops!

Aside from sharing the sex of her second child, Jessica also opened up about how her best friend, CaCee Cobb, who is married to Scrubs actor Donald Faison, is also pregnant.

“We want our babies to be best friends, because we are,” she said. “So now we’re going to force them to go to school together, force them to eat sandwiches together. Hopefully it works out, we would be heartbroken if they didn’t get along.”
