At the ceremony, where guests included Bella Thorne and Avril Lavigne, Posey and Phem shared both traditional and handwritten vows and had a monk from Italy officiate.

The reception for the pair, who got engaged on Valentine's Day earlier this year, was filled with different shades of green and natural elements. They even used the beach wood from where they got engaged in Cambria, California, as part of the centerpieces.

Guests, including "lots of Wolf friends," enjoyed a sit-down dinner featuring the "rarest lobster in the world from a remote island," says Posey. They also served a three-tiered lemon cake, Italian cookies and Duke's famous Hula pie.

As for their wedding must-haves, the couple tells PEOPLE, "Good music, good food, lots of dancing and at least ONE Blink-182 song!"

Phem says it was also important to have a photo of Posey's mom at the special event "so we knew she was present with us."

The singer tells PEOPLE she wore the Inca dress by Grace Loves Lace, which she adds was "so comfortable, so beautiful and fit my style perfectly."

"It has a coastal beachy feel to the design and fit. I didn’t want something too elaborate or flashy but still classy and elegant. This dress really felt right for me," she says.

She paired the look with shoes by Bella Belle, which were "all lace and extremely comfortable," as well as jewelry by Belladaar and Stephen Webster.

For her second look, she was styled by Bianca Agrusa with shoes by Giuseppe Zanotti.

The couple danced to one of Posey's mom's "favorite songs" for their first dance: Norah Jones' "Come Away with Me."

They also had music from Disco Shrine and had "a couple of our guests sing their own songs," Posey shares.

Looking forward, the newlyweds say they're most excited about "building a life, doing projects, creating art and babies" in the future, as well as "having a best friend you can laugh with until you die."

"[Marriage] is the ultimate commitment you can only grow from," adds Phem.

They're also looking forward to "relaxing in paradise" during their honeymoon.

In June, Posey shared the couple's exciting engagement news exclusively with PEOPLE.

"We got engaged in Cambria, California. Phem's favorite place," Posey told PEOPLE. "We spend every Valentine’s Day there so it only felt perfect to do it there,“

Added Phem: “It was just us alone on the beach. I should’ve known when he propped his phone up on a rock to film that something was up… but I had no idea.”

Posey designed the ring himself and incorporated Phem's favorite color: green. "It was a total surprise," he said. "All my friends and loved ones kept it a secret and I designed the ring without her knowing, so I’m very grateful she likes it!"

The pair began dating in 2020 after music producer John Feldmann asked Phem to write some music with the actor. "We bonded about singing about our exes," said Posey.

At the time Phem wasn't looking for romance. “I went into it strictly business… I swear,” Phem teased. “The thing I like the best is that we were friends first.”

But before long, they fell in love. And after getting engaged, their connection has only grown stronger.

"I didn’t expect to feel too different when we got engaged, but it really did change. The love felt deeper and just more confident and settled in. I imagine it’ll grow even more when we get married," said Posey.
