And on her new website, the gorgeous new momma shares the very special moment that she told Nick that he was finally going to be a dad — which was made all the more wonderful because she had started to give up hope that she was going to get pregnant.
"Honestly, by mid-December, I resigned myself to the notion that it was not going to be easy for us," she blogged. "So I decided that I had to just 'let go.'"
Vanessa went on to explain that she and Nick had planned a trip to the Bahamas but before she could get on the vacation to relax she had to finish up some projects and then meet her hubby on the Caribbean island.
The night before she flew out she went out to celebrate a friend's birthday and realized that her appetite had dramatically increased and she did not want her favorite martini.
"After dinner something in my gut said, 'Let's go back to the hotel… and pick up a pregnancy test on the way!'"
And her instinct proved correct when she took the test - and a bunch of other tests that she bought confirmed the happy news.
"I was in absolute shock! I had taken a pregnancy test multiple times every month over the past six months, but this one (and the nine others I took that night) was positive," Vanessa wrote. "It was such a beautiful moment. The only thing missing was my husband, of course."
But Vanessa wanted to hold on to the precious secret until she could tell Nick face to face so she could "look into his eyes when I said, 'I'm pregnant' "and added it was "the longest night I can remember.
The Wipeout host finally got to the Bahamas and took the 98 Degrees singer for a walk along the beach.
"I took a deep breath, grabbed his hands, looked him in the eyes and told him, 'I'M PREGNANT!'" she shared.
"He looked at me and asked if I was serious. I said yes, we hugged and then he said, 'I think I have to sit down!' That was Jan. 6, 2012."
And exactly a year later, Vanessa took her now four-month-old baby boy to the exact spot where she told Nick he was going to become a dad and captured the special anniversary on tape — which you can watch below..
