Naomi Lowde-Priestley and Jason Priestley

Jason Priestley is seeing blue.

The former 90210 star and wife Naomi Lowde-Priestley shopped for blue baby items at the Silver Spoon Dog & Baby Buffet in Los Angeles on Friday, including a pair of Stride Rite Pullet boy booties in navy.

“[Naomi] confirmed they were having a boy,” says a source. “They are so excited. They said this is probably it for them because now they’ll have one of each!” The couple are parents to daughter Ava, 22 months.

They also picked out Mabel’s Labels for their daughter and mingled with other celebrity parents including actress Ali Landry, Dancing With the Stars host Samantha Harris and former Blossom star Mayim Bialik. The event will continue on Saturday, when the five-member children’s entertainment group The Jumpitz will perform.

Priestley, 39, and Lowde, 33, announced they were expecting their second child last month.

The two wed in 2005 on Paradise Island in the Bahamas. Among the guests were former costars Jennie Garth and Tori Spelling.
