A source tells Us that the couple got married "in a cottage pavilion under an archway of white hydrangeas and strands of crystals hanging from the trees."
Lanter and his groomsen, including Justin Gaston, (who dated Miley Cyrus in 2009) and E! News correspondent, Jason Kennedy, wore gray suits for the evening. The source reveals that Gaston even performed for the couple -- playing his guitar and singing during the 20 minute ceremony.
"Their vows were personal," the source tells Us. "Matt talked about how Angela is his whole life."
The blushing bride wore a strapless gown that flared out mermaid style with scalloped tulle at the bottom, the source continues, noting that "she was incredibly tan and her hair was swept back in a low pony."
On Friday, June 14, Stacy already changed her Twitter profile picture, showing off her gorgeous wedding day look.
Stacy's bridesmaids, wearing silver dresses, flanked the bride during her big day. After the touching ceremony, guests enjoyed the cocktail hour, where tunes from Backstreet Boys, Bruno Mars and Maroon 5 were played, before heading to the reception, with a "red carpet entrance" waiting for them.
"Inside the tent, there are tables with white hydrangea floral arrangements and hurricane candles," an insider tells Us. "There's a separate section with a lounge set up with white leather couches and ottomans."
A source tells Us that Lanter, a big Star Wars fan, was greeted by people dressed up as Storm Troopers, who joined the couple at the reception, taking photos with the entire wedding party and walking in behind the newlyweds as they were announced to their guests.
"Once the wedding party was introduced, the Star Wars theme music came on," the source tells Us. "The emcee introduced Matt and Angela, 'From a galaxy far away, I would like to introduce for the first time, Mr. and Mrs. Lanter!!'"
After the unique introduction and the couple's first dance, everyone settled into their tables to eat as a live Frank Sinatra-sounding band played classic tunes, adds the source.
According to an insider, the newlyweds will leave for their honeymoon on June 16. At the CW Upfront event in New York City May 16, Lanter admitted there was still plenty to do before their big day arrived.
"We're right in the midst of the crazy wedding planning chaos," he told Us. "A lot of details are still being worked out and I feel like it's crunch time." Lanter had previously said the ceremony would "be outdoorsy. I'm a huge fan of nature and she is, too."
The newlyweds will soon be relocating to New Orleans, where Lanter is shooting his new CW series Star-Crossed (opposite Aimee Teegarden). "We're in the midst of a move," the L.A.-based actor told Us in May. "Picking up everything and going somewhere else -- and getting married! -- it's a cool, fun new chapter in my life."
The couple got engaged during a romantic trip to Paris in May 2012.
