In the midst of her pregnancy for her second child, Vanessa Lachey has been very intent on keeping fit and healthy.

Vanessa Lachey Instagram showed a photo posted by the brunette beauty, saying her personal trainer has been:

'keepin me and baby girl happy & healthy!'

Nick Lachey's wife was reportedly seen by onlookers to be going to a prenatal workout in Hollywood, Friday. Vanessa tried to keep her tiny baby bump as invisible as possible, too.

The 33-year old beauty showed off her wonderful body in skintight leggings. However, Vanessa covered her bludgeoning stomach with her hands, by putting them in her hoodie's front pockets.

The Miss Teen USA 1998 was seen travelling on the way for her workout, without any traces of makeup. This is possibly because she was soon to attend skincare sessions, which has been parts of her daily life lately.

Vanessa Lachey Instagram coincided with Nick's announcement of his wife's pregnancy via Twitter, on July 15, during the couple's wedding anniversary.

The former 98 degrees boy bander's tweet was read as follows:

'Can't think of a better way to celebrate 3 years of marriage to my beautiful @VanessaLachey than this! #family,'

Nick's captioned photo in Twitter showed son, Camden running around a shoreline, with the words "It's A Girl" etched on it.

Nick talked to People magazine to share his joys of parenthood. The singer also revealed a new word his son learned, saying:

'He knows the word 'no' - of course he didn't learn it from me, but he knows the word,'
