We reckon having the 'Boomerang' singer as an aunt must be pretty cool so no wonder her three blonde-haired nieces look so happy in this Instagram shot.
Nicole uploaded the collage of pictures on Wednesday (7 August) along with the caption: " Just spent the past few days with my nieces..They make me so happy! #goofballs."
From the looks of the last picture it seems playing babysitter and doting aunt finally took its toll on the exhausted looking star!
Along with spending quality time with her nieces, Nicole has been celebrating her sister Keala's 27th birthday on 5 August. She posted this picture of the pair together on Instagram with a birthday message.
Incredibly good looking family, right?!
Nicole has been over in the States recently for work, performing the national anthem at a Los Angeles Dodgers baseball game last week.
She'll be back on our shores soon though as production on the tenth season of X Factor continues ahead of its premiere on ITV later this year.
In related XF news, Nicole's been celebrating her former X Factor contestant Jahmene Douglas hitting the number one position in the album charts last month with his debut effort Love Never Fails.
X Factor winners through the years - can you remember all nine?
