The singer-songwriter, 50, issued a public apology to Barack and Michelle Obama on Thursday, saying that her actions at the private event was “so inconsiderate.”
“Mr. And Mrs. Obama, please forgive me for being the ‘terrible guest’ at such a sacred event for your family,” Badu tweeted. “I was so inconsiderate. Thank you for all your love.”
“What an example of ‘how NOT’ to be,” she added, signing the tweet simply, “Erica.”
Obama just celebrated his birthday with an intimate, outdoor gathering of about 200 family members and close friends on the grounds of his 29-acre Martha’s Vineyard estate.
The Obamas originally planned a COVID-safe outdoor party on the grounds, with required testing and other strict protocols for all guests. After the lengthy guest list and other details of the party were criticized, they look, with only friends and close family invited. They also cited the coronavirus pandemic and the rapidly spreading delta variant for their decision.
“This outdoor event was planned months ago in accordance with all public health guidelines and with COVID safeguards in place,” Hannah Hankins, a spokeswoman for the Obamas, previously told PEOPLE. “Due to the new spread of the Delta variant over the past week, the President and Mrs. Obama have decided to significantly scale back the event to include only family and close friends.”
