The Indian cricket skipper took to Instagram to share a sun-kissed picture of the two and tagged Anushka in the post.
"Everyday is a valentine day if you want it to be. You make everyday seem like one for me. @anushkasharma," Virat wrote along with heart emojis.
Dating for a while now, Anushka and Virat have been spotted together in several occasions - with the cricketer attending movie events and the actress going to stadiums to cheer him during the matches.
The two, however, have not publicly confirmed their relationship.
There were also reports that the pair were tying the knot this New Year's eve in Dehradun, which Virat later denied in a tweet, saying, "We aren't getting engaged and if we were going to, we wouldn't hide it. Simple... Since news channels can't resist selling false rumours & keeping you confused, we are just ending the confusion."
