"For all my fans at Wendover last night, the show will be rescheduled, not a canceled show. WORST way ever to kick off a tour.....under anesthesia and a massive infection. Well, onward and upward. It can only get better from here!!! On another note, Happy Saturday."

Last Sunday, the singer blogged about her hospitalization, writing, "The ER at 3am, THAT is an interesting place to be. Feeling much better now, thanks to my husband's best friend who's an ER doc. I've been living in a dental nightmare for 10 months. I'm getting back on track though, I hope. I've had too many detours this year due to dental issues. I'm finally in great hands and being well taken care of. Last night was wonderful, performing to help raise money for the Autry Museum and earlier in the day performing a few songs to help raise money for the cats and dogs at Needless to say, I'm resting today. Thank you all for your support and understanding. The last 10 months of pain are hard for me to wrap my head around. I'm sure it's difficult for you all to understand too. Let's just pray I'm on the mend. I'll see you all on the road very soon."

4. Beyonce Officially Drops Out of 'A Star Is Born'

Beyonce recently confirmed that she's dropping out of Clint Eastwood's A Star Is Born remake, citing both her and the director's busy schedules as the reason.

"I was looking forward to the production of A Star Is Born and the opportunity to work with Clint Eastwood. For months we tried to coordinate our schedules to bring this remake to life but it was just not possible. Hopefully in the future we will get a chance to work together," Beyonce said in a statement.

According to Variety, Eastwood now wants to cast Grammy winner Esperanza Spalding for the role as the young, up-and-coming performer who falls for an older star, though no male lead has been cast. Leonardo DiCaprio, Tom Cruise, Christian Bale and Johnny Depp have all been approached for the role but have seemingly turned it down, Rolling Stone reports.

Eastwood's film will be the fourth version of A Star Is Born, the most recent remake starred Barbra Streisand and Kris Kristofferson in 1976.
