Video: Real Madrid's Cristiano Ronaldo does karaoke during birthday bash

Real Madrid star Cristiano Ronaldo decided to have a sing-song during his 30th birthday celebrations over the weekend.

The three-time Ballon d'Or winner donned a party hat and shared the microphone with Colombian singer Kevin Roldan at the In Zalacain venue on the outskirts of Madrid.

According to the Daily Mail, the party was originally scheduled for the middle of last week, but was delayed by Ronaldo as he wanted to focus on Saturday's game against local rivals Atletico Madrid.

Despite losing 4-0 at the Vicente Calderon, Ronaldo, Marcelo and injured James Rodriguez seemed in high spirits.

Roldan posted a video of the celebrations, which were attended by around 150 people.
