When your friends commit to the Karaoke.

We wanna hang out with Katy Perry and Orlando Bloom!

The super fun duo sang karaoke at a joint birthday party for Ronan Farrow and Westworld actress Shannon Woodward's in West Hollywood on Saturday — and it looks like the crowd had quite the time!

The cuties, and their crew, hit up Blind Dragon, for the song fest. Ronan, Katy, Orlando, Kate Miccucci and more were jam packed into the private karaoke room, belting out tunes like Alanis Morissette’s 1995 hit "You Oughta Know" and Avril Lavigne's 2002 debut single, "Complicated."

Ronan posted an Instagram pic from the bash with the caption, ”When your friends commit to the Karaoke.” In the shot, KP sings into a white microphone as her boyfriend of almost a year parties down nearby. Too fun!

The birthday boy also posted a video from the rousing soiree — and it’s all kinds of fun! We wonder if the gaggle of gorgeous people sang any Katy Perry songs?!
