Ashlee Simpson and Pete Wentz had dinner at Koi in LA on Friday, and then Ash spent some time shopping for makeup on Sunday before glamming up for the VMAs later that night. While Pete's friend Tyga said the couple was expecting twins earlier in the weekend, when we talked to him on the VMA red carpet he laughed it off saying, "Oh I did? I said that? I thought I said they were adopting an African kid. That's what I heard." Ash and Pete's rep also denied the rumor. Whether or not Tyga was joking about the twins it's still fun to see Ashlee take her large bump all around town and we're excited to meet the new Simpson-Wentz addition, however many there may be.
