Laich, 30, and Hough, 25, were seen walking their dogs on a hiking trail while holding hands. The hockey player is on break while his teammates compete in the 2014 Sochi Winter Olympics.
The two seemed to be in a cheery mood on Friday in their Valentine's Day tweets, "Share a kind gesture to a stranger today and show them the true meaning of love. Show love. Be love. Happy Valentine's Day!!" tweeted Hough. Laich seemed in a similarly good mood when he tweeted, "Happy Valentines Day everyone -- hope you are spending it with that special someone who makes you happy! #onelove."
Hough has been single since she broke up with Ryan Seacrest last year.
