Pop star Austin Mahone celebrated his 19th birthday over the weekend with rumored love interest, singer Becky G, who made sure he had the best party ever.

The pair celebrated Mahone's big day with sun, sea, festivities and photos that Becky G posted on Instagram. The "Shower" singer even shared her view of the ocean, captioning the image: "Under the sea. Under the sea."

Mahone's birthday bash was topped with a cake in the shape of a basketball. The "Mmm Yeah" singer and Becky G, 18, also rode around on a pair of personal water scooters. The couple reportedly started getting closer in February after they were spotted flirting during a recording studio session.

Mahone has been busy in the past year, releasing his EP "The Secret" and completing his second headlining tour.

Rihanna's 'Oxygen'

Martin Luther King Jr.'s funeral, the moon landing in 1969, the World Trade Center attacks on Sept. 11, 2001, and last year's riots in Ferguson, Missouri, following the shooting of Michael Brown, an unarmed black teen, by a white police officer.
