Reese Witherspoon celebrated her 40th birthday over the weekend with a blowout A-list party at The Warwick in Hollywood. Your invitation must've accidentally gone to a junk email folder, but thankfully there's plenty of evidence of the lavish party that happened despite your absence. 

Fancy people in attendance included Jennifer Aniston, Courtney Cox, Matthew McConaughey, Taylor Swift, Keith Urban, and, most importantly, Witherspoon's mom.
