Adele doppelgänger who’s setting fire to the bluesy diva’s would-be Las Vegas reign. Janae Longo, a professional hair and makeup stylist, is belting out ballads such as “Easy On Me” and “Someone Like You” in proxy for the British singer, who postponed her much-ballyhooed, four-month “Weekends with Adele” residency at Caesars Palace due to COVID concerns. And Adele devotees who purchased the pricey $800 to $2,000 tickets to her since-canceled showcase can check out the songstress’ impressive impersonator headlining the “Legendary Divas” show at the Tropicana for free through Sept. 5.
