One of Paltrow's pals that was noticeably missing at the event was Kate Hudson. The mother-of-two
recently revealed to ET that Hudson gave Paltrow a valuable beauty tip
. "Kate was the first person who told me to stick my head in ice water when you wake up and you have to shoot something and you've had too much fun the night before," she shared. "She's just the most carefree, lively, loving person and I think a lot of her beauty comes from that."
