A museum in Justin Bieber’s hometown of Stratford, Ontario, already has a display dedicated to him, but now it is getting a revamp.According to the Stratford Beacon Herald, new items will be added to the “Justin Bieber: Steps to Stardom” exhibit at the Stratford Perth Museum, many from Justin himself and his family. Among the new items: the basketball jersey the singer wore last year during NBA All-Star weekend, a photo of him and his wife Hailey, and a pair of The Biebs’ underwear.The undies were a gift that Justin got when he appeared on The Ellen DeGeneres Show, explains the museum’s general manager, adding, “Apparently worn once.”In addition, Justin’s grandfather’s stuffed fox — whose paw Justin broke as a kid — will also be on display in a glass case. It’s the same fox seen in the 2011 concert film Justin Bieber: Never Say Never.When the upgraded exhibit opens this weekend, there will be 60 new items. Over 20,000 people flocked to the facility in 2018 and Bieber has stopped in about five times.

Ariana Grande will no longer be in attendance at the 2019 Grammys this Sunday after a disagreement with producers.The 26-year-old singer – who was set to attend and perform – felt “insulted” after producers refused to let her perform “7 Rings” during the show, an insider told Variety. The source went on to say that Ariana and the producers reached a compromise where “7 Rings” would be part of a medley, before Ariana pulled out after producers insisted that the second song would be one that they chose.Ariana is nominated for two Grammys – Best Pop Solo Performance for her song “God is a Woman” and Best Pop Vocal Album for Sweetener.Meanwhile, Ariana gave her “7 Rings” music video director, Hannah Lux Davis, a Tiffany’s diamond ring of her very own. The special moment was captured in a new behind-the-scenes video from the music video’s set.Ariana presented Davis with the little blue box and Davis opened it in shock. “No it’s not,” Davis said in disbelief. To which Ariana replied, “It’s 8 Rings now.”The inspiration for the song “7 Rings” came from a trip that Ariana and her friends took to the Tiffany store in New York City on a particularly rough day. Ariana ended up buying all her friends matching diamond rings.
