James Van Der Beek and Kimberly

James Van Der Beek is completely "in love" with his three-week-year-old son Joshua.

The 'Don't Trust the B---- in Apartment 23' star and his wife Kimberly Brook, 30, welcomed the tot into the world on March 13 and he admits he is completely besotted with him.

Speaking at the premiere of 'L!fe Happens' in Century City, California, this week, he said: "I'm just in love. I adore him. You don't realize it until it actually happens and then it's like, 'Oh, that's what they were talking about.' "

However, James - who also has an 18-month-old daughter Olivia with Kimberly - has scoffed at suggestions he named his son after his former 'Dawson's Creek' co-star Joshua Jackson.

The 35-year-old actor didn't even consider the fact his child would be sharing a moniker with his pal - who played James' character Dawson's best friend Pacey in the hit teen TV series, which also starred Katie Holmes.

When asked whether his fellow actor provided the inspiration for the name, James told Us Weekly magazine: "It would have been cute, but no, it's something I did not even think about. It's a great name."
