Ren?e Zellweger is a singleton no more.

After a whirlwind four-month courtship, the erstwhile Bridget Jones' Diary spinster was hitched to country star Kenny Chesney Monday in the Virgin Islands, her publicist confirmed to E!

The freshly minted marrieds--henceforth known as "RenKen"--tied the knot "in front of close friends and family in St. John," said Zellweger publicist Nanci Ryder, who offered few details of the surprise nuptials, other than Zellweger's gown of choice (a strapless Carolina Herrera number).

Chesney went barefoot down the aisle and, ever the cowboy, wore his trusty black Stetson during the 15-minute ceremony.

"I am incredibly happy. I may well be the luckiest man alive," Chesney said in a statement. "To be so in love with someone who is so perfect for me. It's just hard to imagine that I'm not going to wake up."

The wedding reception was held afterward at Chesney's house in the gated community of Peter Bay, on the north side of the island. On Sunday, Zellweger, Chesney and their 50-person party partied at Rhumb Lines restaurant in downtown Cruz Bay, the main town on the island. Per reports, it was during the dinner that the couple made the surprise announcement that they were getting married the next day.

Zellweger and Chesney have only been dating since Jan. 15, when they met at the Concert of Hope tsunami relief benefit, where he performed and she answered phones. She served him his traditional margarita at an Apr. 29 show in Jacksonville, Florida, and last week the couple were spotted getting all kissy at a P.F. Chang's restaurant near Nashville. This week's People quotes Zellweger's publicist saying the twosome "are in the very early stages of getting to know each other."

We can't wait to see what happens once they get past that awkward phase.

This is the first marriage for both.

Zellweger, who turned 36 in April, is eight months over her relationship with another musician, White Stripes frontman Jack White. The Texas-born beauty's other leading men have included her Me, Myself & Irene costar Jim Carrey in 1999-2000 and George Clooney in the mid-'90s. Aside from her Bridget Jones flicks, Zellweger is best known for such films as Jerry Maguire, Chicago and Cold Mountain, the last of which earned her a Best Supporting Actress Oscar.

Chesney, 37, was previously engaged to Mandy Weals, but they split after calling off their wedding in 1998. One of Nashville's biggest acts, Chesney won Entertainer of the Year at the Country Music Association Awards last November. His latest album, Be As You Are: Songs from an Old Blue Chair, debuted atop the Billboard Hot 200 in February. It was his third straight chart-topper, following 2004's When the Sun Goes Down and 2002's No Shoes, No Shirt, No Problem.

According to Country Weekly magazine, Chesney long ago named Zellweger as his favorite actress and was inspired to write his 1999 hit "You Had Me from Hello" after her famous line in Jerry Maguire.

The newlyweds' honeymoon will be over soon, however. Chesney is due in Little Rock, Arkansas, on Thursday for a concert and is slated to perform at the Academy of Country Music Awards on May 17, while Zellweger hits the PR circuit later this month for her new film, Cinderella Man, which is due in theaters June 3.
