And while pictures speak a thousand words, photographs of the duo holidaying in Spain are doing the rounds.
The couple, who were spotted at a music concert in Ibiza, were snapped enjoying a sunny day at the beach on their Spanish holiday, right before Katrina's birthday.
The pictures reveal a toned looking Katrina in a white and red bikini with Ranbir Kapoor cooling off in a pair of surfer shorts.
On their return from Spain, Ranbir and Katrina were spotted attending some film screenings together in Mumbai.
However, they have been photographed by fans yet again, at a coffee shop, this time in Sri Lanka.
Looks like the lovebirds have finally decided to come out in the open about their sizzling romance, which no doubt has everybody interested.
