When you’re friends with Rihanna, you can guarantee a good time. The pop star celebrated her BFF Melissa Forde’s birthday on Thursday, documenting the festivities on Instagram.
“Today is one of the most important days of my life. The day my sister was born!! HAPPY BIRTHDAY M$$,” she tweeted.
The day kicked off with Rihanna bursting into Melissa’s bedroom with a cake in hand. After catching her in her pajamas, they hugged and took pictures as RiRi paraded around in her pink robe.
“Haaaaa!!!! Got you!!! In to pannies and all,” said a sneaky RiRi.
The celebration continued on the tour bus en route to San Diego for Rihanna’s “Diamonds World Tour.” They decorated the bus with banners and balloons, drinking and laughing all the way to the venue.
