Have you ever wondered what celebrities do in their free time? Many celebrities were reported loving singing karaoke. Well, why wouldn't they? Here's some people we'd have join our Singa karaoke parties any day.

1. Katy Perry

Ah, a famous singer does karaoke, how exciting! Well, while you might not be that surprised to find out that Katy Perry sings karaoke, you might be surprised with her karaoke choices sometimes.

Take a look at this time when the multi-awarded singer was spotted rapping Will Smith's Miami at a karaoke bar in California. It was impressive!

2. Rupert Grint

The British actor made famous for his role as Ron Weasley in Harry Potter films rocks out a tune in this very heart-warming karaoke session.

Can you imagine Harry, Hermione or... "He Who Must Not Be Named" grabbing a mic, too?

3. Tom Ellis

When naming celebrities who love singing, you can't forget Tom Ellis. You might also know him as Lucifer Morningstar from the Netflix's hit Lucifer. Tom has lots of karaoke stories to tell and even did karaoke sessions with fans for charity causes.

Here is a short clip of him singing karaoke with the Lucifer's crew.

4. MØ

MØ is a famous Danish singer-songwriter-musician who's been collaborating with Major Lazer, Diplo and Justin Bieber to name a few. She caught our attention with her love for karaoke in the article by Noisey, which reported about an evening the editor and the superstar had spent inside a karaoke box. And apparently "shit got wild".

We love the fact that MØ wanted to sing the iconic Millenium young-love song "Teenage Dirtbag".

P.S. The singer mentioned that there had been not many karaoke places in Denmark. Fortunately, that's changed! Check out this cool karaoke box venue called City Pop.

5. Robert Pattinson

Let Gotham City know: Batman sings karaoke! In fact, Pattinson is known to be very engaged with music. He was in a band, plays guitar, writes music, sings karaoke. The actor is that celebrity who has karaoke parties frequently at his own home!

His favorite karaoke song, you ask? It's (was) Angels by Robbie Williams.

6. Sigrid

The Norwegian "Don't Kill My Vibe" singer Sigrid had such a fun-looking karaoke session at Way Out West festival in Gothenburg this August.

6. Natalie Portman, Emma Stone and more

Literally, celebrities are just like us. Some love karaoke and some don't (yet). Some are good at it, some are not. Regardless, we are here for more celebrity karaoke content!

Some celebrities love karaoke so much that they can even straight-up name their go-to karaoke songs.

How uplifting it is to know that Ewan McGregor's karaoke go-to is also Angels by Robbie Williams and Natalie Portman sings Milkshake. But yeah, obviously we are sad that Ryan Gosling doesn't have a karaoke favorite. I suggest him trying All of Me in the style of John Legend.
