Lady Gaga and her tatas wish Naomi Cambell the happiest of birthdays.
The "Bad Romance" singer took to Instagram on Monday to wish Campbell a happy 47th birthday, with a pic of herself topless in the kitchen.
"🍴🍳 #HappyBirthdayNaomi @iamnaomicampbell," Gaga wrote alongside the snap, which hid her breasts but showed off her back tattoos.

ET caught up with Campbell earlier this year, where she opened up about embracing the new generation of supermodels like Kendall Jenner and Bella Hadid. 
See what she said in the video below.
