Lily Aldridge stopped by Us Weekly's offices so that we could test her knowledge about her inner circle … and the Victoria’s Secret Angel, 30, got stumped!

Did she know which pal wore a blush Marchesa gown at her wedding? Her single girlfriends Taylor Swift and Selena Gomez couldn’t be culprits, so she guessed Chrissy Teigen (who chose Vera Wang, for the record) — completely forgetting that it was Behati Prinsloo

“I was there!” Aldridge laughs. “It must’ve been the sun … I couldn’t tell.”

The model, who’s married to Kings of Leon rocker Caleb Followill, was also asked about which friend has a hairless Sphinx cat … and which comrade would drop everything and call her mom just to have a conversation.

If the suspense is killing you, watch the video above to find out these answers and more!
