Miley bared her gap-toothed smile in the photos, which were taken when she was only seven.

The future actress and singer had baby Noah swaddled in blankets and cradled in her arms as she sat on a sofa that dwarfed her. 

She wore an orange, white and black striped sweater with black pants and white trainers, and her new sister had an ‘X’ drawn on her head in red marker.

‘Happy birthday to an icon living @noahcyrus,’ Miley initially captioned the photos. 

Later, she came back and added a lengthier message about her baby sister.

‘I love you baby sister turned big sister. The day you were born I never knew that one day the roles would be reversed and you would be the one taking care of me,’ she continued.

‘You were such a rockstar thru the experience of losing Mary Jane. I couldn’t have gotten here without you.

‘You lead me to making the hard but right decisions. You’ll have many more of those choices in your own life & I am here for you every step of the way. ✝️ love you always,’ she wrote.

Miley ended the lengthy caption with some words of wisdom for her sister now that she was legally able to drink alcohol.

‘Happy 21st. Don’t get near as drunk as I did. I practically missed my own party cause I spent the night over the [toilet and vomiting emojis],’ she wrote.
