Jessica Simpson's first pregnancy has been a breeze -- so far.
"I feel great, I honestly do," the 31-year-old star told Access Hollywood's Billy Bush on Tuesday.
"Pregnancy is a friend of mine, so everything has been running smoothly," Jessica, who was promoting her new Beauty Mint skincare line, continued. "So far, so good - no morning sickness. I feel great. I'm tired, but you know, I'm making a baby here!"
The mom-to-be did reveal a few changes that have happened to her body, saying she's had "swelling in the belly and boob area."
Jessica - who announced her pregnancy last month after much speculation - revealed that she decided to take the test without first telling fiance Eric Johnson.
"I did the pregnancy test. I was feeling a little off," she recalled. "[I first told] Eric, of course. He was in the house. He didn't know that I was taking a pregnancy test, so I kind of shocked him. I came in shaking like, 'Oh my gosh! Oh my gosh! This is happening!' We both cried. We were in shock and kind of just sat there and stared at each other."
Jessica and the former NFL player, 32, will welcome their new addition to the family in 2012.
"I am having a spring baby," she told Billy. The happy couple announced their engagement in November 2010. Previously, they said they hope to wed by Christmas 2011, but Jessica told Billy they now plan to push their nuptials back. "We were going to throw something together, but I'd rather put more time in it and be able to really enjoy the day," she continued. "When you're pregnant, your hormones go crazy. I don't want to be super stressed out and end up being a bridezilla! So, I'll wait until after."
The singer/fashion mogul and upcoming star of NBC's "Fashion Star," said her days of being in front of a camera 24 hours a day appear to be behind her.
"Letting everybody in on every detail of your life, that's a hard thing to do," the singer explained. "I feel like, for me, those days are over, but I can always be who I am on camera... I'll always be myself."
