Irina Shayk for Love Magazine’s Christmas Special

What will Cristiano Ronaldo say? Irina SHAYKs her bottom in day 19 of LOVE Magazine's advent calender

Russian model Irina Shayk is the festive treat in day 19 of the LOVE advent calendar, writhing around in Calvin Klein and playing with fairy lights.

The 27-year-old star, who is currently dating 28-year-old Real Madrid footballer Cristiano Ronaldo, sings an acapella version of Marilyn Monroe's Santa Baby.

Wearing just a pair of briefs and a lacy bra the star dances around as she muddles her way through the song.
