The "John Wick" star's longtime girlfriend Alexandra Grant shared a glimpse at the romantic way she rang in his 61st birthday Sept. 2.

Grant, 52, showed off a heart-shaped cake covered in white frosting and outlined with candles as well as black and white candies. The dessert also featured "KEANU X" inscribed in red gel icing.

Alongside the pic, the artist offered a message to fans assuring them that the "Matrix" actor felt the love on his big day.

"Thank you to everyone for sending over sweet wishes for Keanu's birthday yesterday," she captioned the Sept. 3 Instagram post. "He was well-celebrated!"

Grant also shared a touching message to her longtime love, noting that he did in fact see it despite not having an account on the platform -- or any other social media channels.

"To Keanu -- who saw this post as a draft! -- I am so grateful for your love and partnership," she gushed. "Now back to painting! Xo."
