Vanessa Lachey's love letter to son

Vanessa Lachey says her son Camden makes her relationship with her husband Nick so much better.

Nick and Vanessa Lachey's son makes their life together ''much more beautiful''.

Vanessa gave birth to Camden five months ago and in a heartfelt letter to the tot on his first Valentine's Day (14.02.13), she revealed how he has changed their lives.

She wrote: ''Cam, This Valentine's Day you'll only be 5 months old, but I feel like I've loved you forever,'' Vanessa wrote. ''I have wanted to be your mommy for as long as I can remember. Nothing in this world could ever compare to the way you make me and your daddy feel every day.''

''Words can't even begin to express how much more beautiful you make our life together. As you grow and take in this world around you, know that you are loved today everyday all because you're you! Sweet precious little you. Happy First Valentine's Day (sic).''

Nick, 39, recently revealed he plans to take Vanessa, 32 and Camden with him when he reunites with his group 98 Degrees for a summer tour with New Kids on the Block and Boyz II Men.

He said: ''Camden will be on tour for sure. I'm not going to spend 2 1/2 months away from my son. That would be tragic.
