Ariana Grande was angry on Sunday evening when her late beau Mac Miller did not win a Grammy award.

But the day before the big show, the beauty appeared to be in great spirits.

The former Disney princess was seen celebrating her big success with her latest album Sweetener – which came it at number one during its first week on sale – as she downed champagne in Beverly Hills with friends.

The siren had her brunette hair in a long ponytail, her usual look, with a beige jacket over a beige tube top and a black choker on.

And the star added green cargo pants and platform boots with a Chanel belt purse.

She was made up to the nines with black eyeliner and pink lipstick suggesting she was ready for a photo shoot. And the petite wonder wore her nails long and light pink.

There were several friends around her, both men and women.

Monday morning, Ariana lounged in bed as she reflected on her first Grammy win, following six nominations.

‘It’s me your tiny, highly emotional, italian, and now grammy award winning friend. i’m super tarnished lol. but super grateful,’ she wrote.

She then shared a photo of herself lying in a darkened room, writing: ‘sry if i’m up n down a lot’.

This was swiftly followed by yet another apology – this time for saying sorry too often.

‘n sorry if i say sorry way too much,’ wrote the 25-year-old.

On Sunday, Grande took to Twitter to vent about the Grammys and her late ex Mac Miller on Sunday, then later deleted the tweets.

The Boca Raton, Florida native, boycotted attending the ceremony amid a creative rift with producers, but was active on social media throughout the day – showing fans the Zac Posen gown she would have worn – before later deleting most of the stream-of-consciousness content she had posted.

Grande hit a boiling point when Miller was not named as the winner in the Best Rap Album category for his album Swimming, losing out to Cardi B’s Invasion of Privacy.
