Love has a way of bringing out the artist in Sarah Geronimo. For the invitation to celebrate her boyfriend Matteo Guidicelli’s birthday today, hosted by Swatch, the country’s hottest star drew a portrait of Matteo and signed it “Mahal Ko, SG.”

Matteo is one of Swatch’s hottest endorsers. His romance with Sarah is one of the most talked about in show biz, and for good reason: Not only are they an attractive pair through and through, Matteo is also the Pop Princess’ first official boyfriend. Now she’s proclaiming her love for him to the world.
