Music Notes: Mariah Carey, Justin Bieber and more

It's another chart record for Mariah Carey. Her song "All I Want for Christmas Is You" has just racked up its 20th week on top of Billboard's Streaming Songs chart. That ties the record, set by "Old Town Road" by Lil Nas X and Billy Ray Cyrus, for the most weeks on top since the chart debuted in 2013. In other Mariah news, after canceling three concerts due to the flu, she told fans she's on the mend and will be able to perform the final show of her Christmas tour Dec. 17 in Brooklyn.

Justin Bieber and wife Hailey have yet to show their son Jack Blues' face on social media, but Hailey's dad, Stephen Baldwin, is happy to tell us how adorable he is. Speaking to People, the actor said, "He's just a little muffin and he's eating like a pig and looking cuter than ever." Justin and Hailey announced Jack's arrival with an Instagram post on Aug. 23.
