Stars descended on Martha’s Vineyard Friday ahead of former President Barack Obama’s 60th birthday party, after his spokeswoman claimed the Saturday bash would be scaled back to include “only family and close friends” amid COVID-19 concerns. Celebrity couples such as John Legend and Chrissy Teigen and Dwayne Wade and Gabrielle Union were spotted arriving on the Massachusetts island in pictures obtained by The Post. Teigen, who has recently come under fire for past bullying comments, was seen cradling the couple’s 3-year-old son Miles, as her singer hubby helped unload a white van.
