Kylie Jenner spent Sunday night partying with pop star Nicki Minaj, who celebrated her 31st birthday on Sunday night. The party took place at Phillippe Chow in Beverly Hills. Nicki celebrated the evening with a naughty sex cake- a pair of naked breasts with “Shake Yours for Nicki” and “Happy Birthday” written in icing.

On her Instagram, Nicki posted her other birthday sweets – the clean ones – cakes made in the shape of a microphone, pink of course, and a Tiffany box. Nicki shared a few more fun snippets from her birthday fete on Instagram – her kinky present, a stripper pole (50 Shades of Grey would approve), and that she was “GONE” that night!

No word on whether 16-year-old Kylie was a goner too.
