The former Dawson's Creek star wed Kimberly Brook in a private ceremony in Tel Aviv, Israel last month (Aug10), and the couple decided to share its joy with close pals at a second celebration in Los Angeles at the weekend.
Brothers & Sisters star Getty and his wife Rosetta stepped in to act as hosts and they opened their home to Van Der Beek and Brook's family and friends, including Demi Moore and Ashton Kutcher.
Guests at the low-key event were treated to sushi, mini burgers and salad.
A source tells People.com, "The party was very small and intimate... James and Kim were glowing. Despite being about to burst, Kim looked amazing."
Brook is due to give birth to the couple's first child later this month (Sep10).
Van Der Beek was previously married to actress Heather Ann McComb.
