LOS ANGELES (AP) -- Though Ashlee Simpson and Pete Wentz are keeping a tight lid on their nuptuals, it's looking like a wedding is imminent.

Aerial photos posted Friday at several celebrity Web sites, credited to the Insight News & Features paparazzi photo agency, purport to show the Simpson family home near Los Angeles dotted with large white party tents.

People.com reported that Wentz and Simpson's father, Joe Simpson, had dinner Thursday night at celebrity eatery Mr. Chow before celebrating the Fall Out Boy bassist's bachelor party. The Web site posted photos, also credited to INF, of the two emerging from the Beverly Hills restaurant Thursday, saying they were partying "days before" the wedding.

An Associated Press reporter witnessed more than 30 photographers waiting outside the restaurant Thursday night.

Simpson's publicist declined to comment on the couple's wedding plans.

"This is a private matter," Rhett Usry said in an e-mail to The Associated Press. "There is nothing to confirm at this time." A representative for Fall Out Boy told the AP that she had no information.

Simpson, 23, and Wentz, 28, began dating in fall 2006 and announced their engagement April 9. Rumors that Simpson is pregnant soon followed, but the couple has denied that they are expecting a child.

Simpson, a singer, songwriter and actress, is the younger sister of pop star Jessica Simpson. Ashlee Simpson's latest album, "Bittersweet World," was released last month. It peaked at No. 4 on the Billboard 200 in its first week, and tracks have logged more than 19 million plays on her MySpace page.
