WATCH: Sonny Bill Williams sings to hospital staff after surgery

He’s starred in both rugby codes and tried his hand at boxing, but it seems Sonny Bill Williams’ talents are not confined to the sporting arena.

The New Zealand international centre will miss the upcoming series with France due to a knee injury, which required surgery.

But Williams seemed in high spirits after the operation as he still felt the effects of his medication, deciding to treat the hospital staff to a song.

Williams’ ditty of choice? All-4-One’s ‘I Swear’. We’ll let you be the judge of his vocals…

Okay team- here it is. I just want 2 reiterate again that the meds they give you for surgery are very strong and take a while 2 wear off…but I also feel like the staff took advantage of me (I’m joking ) thanks 2 the nurses/staff for putting up with me haha! Blessings fam pic.twitter.com/b1vhUXnFJj
