Nick Lachey jeans the grove autographs

We caught up with Nick Lachey at The Grove on Tuesday, where the newly 38-year-old (his birthday is Wednesday!) former boy band-er graciously signed autographs for fans.

When he and wifey Vanessa Minnillo, 31, got married in July, we thought a pregnancy announcement would soon follow! After all, Vanessa's Twitter profile reads, "Wanna-be Mommy all the time."

But Lachey told E! on Tuesday that he and his new bride aren't in a rush to have kids. "We both look forward to a family but there's no real time table for that stuff," he said. "Just whenever it happens it does and that'll be a great day."

We're surprised! Even though the two dated for five years before marrying, Nick said they want to enjoy some time as newlyweds. Interesting ...
