Before his farewell address, US President Barack Obama plans a farewell bash on Friday night to celebrate the end of his presidency.
While the White House isn't saying who's on the guest list, Chicago-based hip-hop artist Chance the Rapper said on Wednesday on Facebook and Twitter that he was about to fly "21 hours to DC to bid farewell to the greatest president in US history. God bless you (at)Potus."
Chance had been touring in Australia and New Zealand.
Many other celebrities are expected to attend what's shaping up to be the Obamas' final party before the January 20 hand-off to President-elect Donald Trump.
Beyonce was among the celebrities who attended Michelle Obama's 50th birthday party at the White House in 2014.
Obama plans to deliver a farewell address on Tuesday in Chicago.
