her social media today. It's unclear whether she was invited or just unable to go as she continues to prepare to do her Las Vegas residency later this year.

Adele's absence comes after reports this weekend said she is close to finalizing a new Vegas residency deal. TMZ reports that Adele is in “serious talks” with Planet Hollywood for its Zappos theater after her residency at Caesars Palace's The Colosseum was canceled.

Adele spoke on the Graham Norton Show in February about her delayed Vegas residency. “It is absolutely 100 percent happening this year. It has to happen this year because I've got plans for next year,” she said. “Imagine if I have to cancel because I am having a baby!”

Adele added that after her Vegas residency, she will step out of the spotlight again. “I definitely will but I am trying to make a conscious effort to stop being so anal with my privacy,” she said. “I'm trying not to be two completely different versions of myself. It is exhausting switching on and off. I will be disappearing in terms of my music, but you might see a glimpse of me now and then and I won't be in complete hiding.”

“It takes me a while to recharge, and I would like to have more children—I only just feel like I've caught up with my sleep from nine years ago when I had my son,” she finished.
