British singer, Adele has been working on her weight loss for a while now, and it seems things are working out for the Grammy award winner.

The songwriter took to Instagram to share photos from her private Christmas party.

In one black and white photo, she was standing back to back with a costumed Grinch wearing a Santa suit and grinning broadly.

Another photo in the slideshow features Adele smiling with Santa Claus himself.

She captioned the post:

“We both tried to ruin Christmas but then both our hearts grew! Thank you for coming to my party and making us feel like kids Grinch? Merry Christmas and Happy Holidays everyone x.”
