When Celine Dion returned to the stage at Caesars Palace on May 22 for her first concert since undergoing ear surgery two months ago, she told her adoring fans, "I have to admit, I can barely stand on my feet tonight as I am a little bit nervous." The Las Vegas crowd had no trouble leaping to their feet for multiple standing ovations, though, confirming the Grammy winner is back and better than ever.

In March, Celine, 50, shocked her fans when she revealed she was suffering from Patulous Eustachian tube, a disorder that caused hearing irregularities and made it difficult for her to sing. But, her first post-surgery performance allayed their fears.

"Everything with the surgery went well and she's feeling great," a friend exclusively assured to Closer Weekly. "The results of the procedure should be permanent. We'll know more pretty soon, but right now she's not experiencing any side effects." That's great news for the singer, who soon heads to Asia with sons René-Charles, 17, and twins Eddy and Nelson, 7, for an Asia-Pacific tour that kicks off June 26 in Tokyo.

"Her schedule was designed to give Celine and the boys several days off in between performances so she can rest, recover, and they can have time to sightsee as a family," a second friend noted. Her kids were a big comfort to Celine during the time she couldn't sing. "She got to spend plenty of time with them," the pal added.

"She's the ultimate hockey mom, and all three boys love to play, so watching the Vegas Golden Knights team in the NHL playoffs together was exciting for them all!" the first friend continued. Now, having them by her side as she returns to the stage is the best of both worlds for the working mom, who is grateful for all of her blessings. "I don't take anything for granted," Celine insisted.
