Cupid's favorite holiday is here. On Friday, celebrities got into the lovey-dovey mood as they posted sweet messages for their significant others. Cara Delevingne shared a PDA-filled photo with girlfriend Ashley Benson (while raising awareness of Stand Up To Cancer's "Kiss Cancer Goodbye" Valentine's Day initiative), and Justin Timberlake posted an adorable throwback picture with wife Jessica Biel. Kevin Jonas also gushed over his wife of 10 years, Danielle, while Keith Urban and Nicole Kidman celebrated their 13th Valentine's Day as spouses. And John Legend's ode to Chrissy Teigen's feet on The Ellen DeGeneres Show might take the cake for the most unexpected V-Day tribute. There's plenty more love where that came from, so scroll ahead to see more romantic shout-outs from stars!
