Is Selena Gomez's your Roman empire? Do you scroll through your nail mood board only to realize that Gomez makes up half of it? If the is your inspo for all things nail art-related, then you have one man to thank: Tom Bachik. As a celebrity nail artist, Bachik has worked with Gomez for years and is constantly innovating. He is as humble as he is talented, and the renowned manicurist doesn't take sole credit for coming up with these viral-worthy creations.

He says every look we see and love is truly a team effort. "Selena is super collaborative when it comes to and we both brainstorm ideas," Bachik tells PS. "She will be set on a vibe or mood for the look.

Maybe she wants it to feel elegant, sexy, fun, or happy — that will determine the direction for the entire nail look." Gomez is pretty open to any color or , he says, but she definitely has her go-tos. She likes a sheer nude — "Basically a no-makeup, makeup look for nails," he says — or deep pops of color like a that she wore for "13 Reasons Why" premiere a few years ago; it's of his favorites to date.

She's also a fan of shimmers, chromes, and glazes to elevate her nail looks. Anything goes as long as it feels right. "There's no trend or color she wouldn't do," he says.

"It's just about fitting the vibe or mood." We get fed a lot of nail how-tos and advice, so it can be hard to figure out what's worth following and what's actually B.S.
