Over the weekend, Madelaine Petsch started prepping for her 25th birthday on Aug. 18 by treating herself to a fun french manicure. Celebrity nail artist Tom Bachik, who boasts stars like Selena Gomez and Jennifer Lopez as his go-to clients, gave her an abstract negative-space nail design.

Petsch's birthday nails have all of the components of a great transitional summer-to-fall manicure. It's a classic french nail design but with a twist – instead of white or even a single colour of nail polish on the tips, she went with shapes of pastel green, blue, pink, and yellow on a clear base. (This helps the design grow out nicely, which is a must during this time.)

Aside from the unique hand-painted design Bachik created, we can't stop staring at Petsch's beautiful, long, natural nail shape. She's clearly ready to celebrate her 25th birthday with that mani.

Get a closer look at the nail art design ahead.
