Canadian singer Michael Bublé celebrated his wife’s birthday with karaoke, calling her “the greatest person.”

Argentine actress and new Canadian citizen, Luisana Lopilato, celebrated her 37th birthday with heartwarming tributes from her husband, Canadian singer Michael Bublé. The couple shared glimpses of their celebration on Instagram.

On Lopilato’s special day, Bublé took to social media with photos capturing his wife and their joyful moments together. In one post, Bublé shared a carousel of images featuring the couple in various loving poses.

The caption read, “Happiest of birthdays to my smoke show of a wife! You’re the absolute greatest person I’ve ever met!” The “Haven’t Met You Yet” star then quipped Lopilato is “an 11 who agreed to marry a 6.8 and for that I am eternally grateful.”

Lopilato responded to the post saying, “Te amo mi amor! Waking up next to you and our munchies is my best gift! I’m so blessed!” along with a heart emoji.

On her own Instagram, Lopilato shared a reel capturing candid moments from her birthday party, including clips of the couple singing karaoke, dancing with friends and blowing out candles. She added this was just “part one” of her celebrations.

“I’m so happy to have celebrated another year with my dear friends from Canada. The celebration continues in Argentina! See you there,” she captioned the post. “Thanks to everyone for the love.”

The actress received congratulatory messages from fans and followers.

“What a fantastic celebration for a fantastic human,” one Instagram user wrote.

“Congratulations, Lu! I love your vibe! Keep shining,” another added, while someone said: “How beautiful it is to see happiness! Happy birthday Luisana big kiss to Michael.”

In the fall, Lopilato shared her big achievement of becoming a Canadian citizen. She reflected on the milestone and expressed her gratitude saying:

“Becoming a Canadian citizen has been one of the greatest joys of my life… Thank you Mike and my children for supporting me with every exam! Also thanks to my family from Argentina… Finally, thank you Canada for making me part of this wonderful nation.”

Earlier this year, Lopilato and Bublé had a “magical” dinner date with Meghan Markle and Prince Harry at Vancouver restaurant “Vij’s.” The restaurant’s chef revealed to People in February the couples were “extremely friendly and nice,” adding “they were very respectful to let me choose the meal as the chef.”

Lopilato and Bublé’s relationship has always been in the public eye. The couple met in 2008 in Argentina, got engaged in 2009, and were married in 2011 in Buenos Aires; they held a second wedding in Canada the same year. A friend of the couple reportedly told People that it was “love at first sight” for Bublé.

Their family has since grown and they’re now parents to four children: Noah, Elias, Vida, and Cielo.

Their journey has not been without challenges, notably when their eldest son, Noah, was diagnosed with liver cancer in 2016. The couple has been open about this difficult time, and in 2016 “put their careers on hold” while Noah was undergoing treatment in the U.S.
