Gaudencio Sillona III (born February 1, 1981), known professionally as Jay R, is a Filipino-American singer, songwriter, record producer, actor and model. In 2003, he released his debut album, Gameface, under Universal Records. The album was certified platinum by the Philippine Association of the Record Industry (PARI), receiving numerous awards and earning him the number one single, "Bakit Pa Ba".

Jay R was dubbed as "R&B Prince" in his early career and was often partnered with Kyla (then known as the "R&B Princess"). Collectively known to their fans as "JayLa", they are known in the music industry as the R&B Royalties (R&B King and Queen, respectively). In 2006, he built a recording studio inside his mansion, followed by a recording label called JAYRS Music. He later renamed it as Homeworkz Records. In the same year, he released a Christmas album, Christmas Away from Home, and dedicated it to his late uncle Reny. The album was re-released in 2008, where he donated the proceeds from the sales to GMA Kapuso Foundation. Also in 2008, he released a cover album, Soul in Love, which became his highest-rated and biggest-selling album. He made his big screen debut in the 2004 feature film Happy Together, and later, released his self-titled second album in 2005.

He released an all-Tagalog album early in 2010, Jay R Sings OPM Love Classics, which consists of revivals of Original Pilipino Music love songs. Later, he recorded a Bahasa song, which is slated for release in Indonesia. He is part of TV musical variety show Party Pilipinas on GMA, and hosts the Philippine adaptation of dating game show Take Me Out on the same network.

After more than 10 years of being with GMA Network, he transferred to the rival network, ABS-CBN in 2014. After more than three months, he joined the impersonating competition Your Face Sounds Familiar as his first reality show in the network.
