Sam Rockwell has won big in Oscars, as he bagged the best supporting actor award. This may be credited to his lucky charm, the $5,500-Leslie Bibb cufflinks.

Rockwell's performance as Jason Dixon on Three Billboards Outside Ebbing, Missouri continued to gain acclamation. It can be remembered that he also won in SAG and Golden Globes early this year for the same film.

His Oscar win on Sunday can be cited to his exceptional portrayal and also to his charm, his longtime partner, Leslie Bibb. In addition, his cufflinks with his sweetheart's name probably played some role in the fate of his victory.

Before they grace the Oscars, stylist Michael Fisher took to Instagram to share a photo of Bibb and the cufflinks created by David Yurman. Rockwell sported a tuxedo by Prada and a Christian Louboutin shoes to the awards night.

His accessory cost $5,500 and was made for a month. Bibb opted for a dress by J. Mendel. Meanwhile, Fisher told People that Rockwell is pretty much involved with his outfits. The Iron Man actor also makes sure to have his and Bibb's outfits coordinated.

"Leslie works with [stylist] Jeanann Williams, we would text images from our fittings to make sure Sam and Leslie were in-sync. It was very important for all involved that they complemented each other," the stylist said.

Recently, the couple surprised everyone when they admitted they have been together for more than 10 years.

"Communication and good sex," paired with sense of humor, these are the secrets to a happy and lasting relationship, according to Rockwell and Bibb.

2018 Oscar Win

Rockwell's 2018 Oscars is probably an exhilarating and unbelievable experience, as this was his first time getting the gold statuette. He dedicated his win to deceased Philip Seymour Hoffman, who he said became his inspiration, and his parents.

He bested against other nominees such as Richard Jenkins for The Shape of Water, Willem Dafoe for The Florida Project, Woody Harrelson in Three Billboards in Ebbing, Missouri, and Christopher Plummer for All the Money in the World. The best supporting actress is Allison Janney for I, Tonya.

Celebs React   

Not only did he win critics' hearts, he also won the other celebrities who took it to Twitter to extend their congratulations to Rockwell. Baywatch actor Zac Efron and singer Hailee Steinfeld sent their messages for the acclaimed actor.

Captain America star Chris Evans described Rockwell as "a rare and phenomenal talent" and "one of the most unpretentious human beings."
