Happiest place on Earth! Céline Dion treats sons to Disneyland visit as they celebrate the twins' first birthday since father René Angélil's death

It's been a tough year for Céline Dion, who lost both husband René Angélil and brother Daniel to cancer.

But the 48-year-old was determined to keep her spirits up as she treated her sons to a Disneyland visit days after twins Nelson and Eddy's sixth birthday, the first since their father had passed away. 

She looked to be enjoying herself at the happiest place on Earth, where she and her sons took in attractions such as Dumbo the Flying Elephant, King Arthur Carrousel, Storybook Land Canal Boats, and Mad Tea Party. 

Keeping their spirits up! Céline Dion treated her sons to a Disneyland visit on Tuesday, likely to celebrate sons Nelson and Eddy's sixth birthday, their first without late father René Angélil

Classic: Céline was also seen smiling alongside eldest son René-Charles on King Arthur Carrousel, which they reportedly rode multiple times

Céline looked chic in a billowing, white blouse with short sleeves, teaming it with a pair of skintight, white jeans.

She kept comfortable in a pair of white, slip-on sneakers, accessorizing with a small, black leather cross body bag.

She wore her long, blonde tresses slicked back into a sophisticated bun, and kept her make-up simple.

The mother-of-three seemed to be having a blast as she and her sons took in some of Disneyland's most beloved rides.

She showed off a smile and was seen laughing and throwing her hands up in the air as she rode the Mad Tea Party with one of her twin sons, who just celebrated turning six on October 23.

They were spotted excitedly spinning around in a teal teacup on the dizzying, Alice in Wonderland-themed ride.

She also threw her arms in the air as she sat beside one of her sons on Dumbo the Flying Elephant.

Céline laughed as she chatted with eldest son René-Charles, 15, while they sat side by side on horses riding King Arthur Carrousel.

The cheerful family outing comes after Céline's emotional CBS Sunday Morning interview about her late husband, which aired earlier this month.

Céline and René officially began dating in 1987, when she was 19 years old and he 45. They were engaged by 1991, and married in 1994.

When asked by interviewer Mo Rocca if she hoped to fall in love again, the star answered: 'Not now.'

'I'm still married to him,' she said of her late husband, adding: 'I've never kissed another man in my life.'

The father of Céline's three children passed away in January after a battle with throat cancer.
