Neyo's Birthday Party Brings Out Rihanna, Jay-Z

Singer/songwriter Neyo had plenty to be thankful for earlier this week, as he celebrated his 25th birthday in style at the swank Tribeca Rooftop in NYC.

The Las Vegas native, whose credits include writing top hits for Beyoncé, Rihanna and Whitney Houston, among others, enjoyed a guest list that included Jay-Z, LL Cool J, Janet Jackson, and Ray J.

Adding to the collection of A-listers in attendance, Rihanna showed up fashionably late, as did fellow Def Jam artist Chrisette Michelle, who "serenaded the singer with a rendition of 'Happy Birthday' before he cut his red-velvet cake and passed it around to the crowd."

Meanwhile, waitresses dressed as Playboy bunnies made sure that all of the glasses and plates were filled.
