Chance The Rapper helped Beyonce celebrate her 35th birthday on Sunday (04Sep16) by leading a singalong at the Made In America festival.
The birthday girl spent her special day with her husband Jay Z at his annual two-day music gathering in Philadelphia, Pennsylvania, and the couple's friend Chance didn't let the occasion pass him by as he graced the stage on Sunday night.
In video footage posted online, Chance, who refers to the superstars as "Auntie" and "Uncle", sings a unique version of Happy Birthday to the Halo hitmaker, with lyrics including, "Auntie it's your birthday, happy birthday 'Yonce".
He then encouraged fans to join in, as a shy Beyonce swayed to the music behind Jay Z and then buried her face in her husband's back, before applauding the 23-year-old's sweet gesture, which occurred a week after Chance freaked out backstage at the MTV Video Music Awards as the music icon stopped by to say hi.
Beyonce also received a birthday shout out from another close pal, Chris Martin, as the British rocker and his Coldplay bandmates headlined the Sunday concert, which the R&B star enjoyed with her friends Kelly Rowland and La La Anthony, the wife of basketball star Carmelo Anthony.
"We want to say happy birthday to Mrs. Carter, who is out here somewhere," Chris told the audience, before joking, "Can you believe she's 107 years old? Happy birthday Bey!"
Other VIP guests at the final night of Made In America included former President Bill Clinton, who was spotted chatting to Beyonce earlier in the day, and First Daughter Malia Obama, who the singer recently visited at presidential retreat Camp David.
Beyonce and her daughter, four-year-old Blue Ivy, were photographed stepping off a private plane in Frederick, Maryland on Friday (02Sep16), as they joined First Lady Michelle Obama and her daughters Malia and Sasha for a girls' weekend. President Barack Obama was not present for the superstar's stay as he was in China to attend his final G20 summit as leader.
