Madonna shared a snap of the unforgettable moment she celebrated her daughter's birthday, which she captioned, 'Make a Wish Mercy James.'

Wearing a sparkly number and silver heels, the hit-maker bent down on one knee to offer the pastry to her adopted daughter.

Mercy appeared through the moon by the gesture. 

The birthday girl wore a black top, light red trousers, and a long gold chain.

It certainly wasn't the only show of love Madonna shared for her daughter that day.

'Happy Birthday to my Beautiful Mercy James!,' she captioned the image.  

Madonna is currently caught up in a nasty legal dispute over the custody of her oldest son Rocco, and has been blasted by fans for a series of disastrous concert dates. 

The star seemed genuinely touched as she thanked her fans for their support with a heartfelt tweet on Saturday.

Reposting a supportive message from a group of fans, she added: 'Thanks soooooo much for this! It means a lot to me! One word of kindness it can save me!'

Banding together, her fans had written an Instagram message pledging Madonna their backing 'whatever the things you're going through'.

The message stated: 'We’re crying for you, but we know you will get through this as you always do. You were born a lion, and lived a lion. We just want you to know that our love for you rescues us every single day, and we hope ours could do the same.' 

Sing it! The 57-year-old no doubt had the crowd in the palm of her hand
