(LOS ANGELES) -- Wedding bells were ringing within the Hollywood community over the weekend.
The Hangover actor Justin Bartha married fitness trainer Lia Smith Saturday in her native Hawaii, according to People magazine. The guests at the Oahu ceremony included Reese Witherspoon and her husband, Jim Toth; Jesse Eisenberg; and Hangover co-star Ken Jeong.
Bartha, 35, was first romantically linked to Smith in early 2013. They announced their engagement last May.
Liam McIntyre, who plays the lead role in the Starz series Spartacus: War of the Damned, got hitched over the weekend, too. The 31-year-old actor tied the knot with Australian singer-actress Erin Hasan in his native Melbourne on Sunday.
McIntyre tells People, "I'm beyond happy!"
The couple got engaged at Walt Disney World in Orlando, Fla., in December 2012.
Finally, Spy Kids and Machete Kills actress Alexa Vega wed Big Time Rush singer Carlos Pena, Jr. in Mexico on Saturday, her rep tells People.
Vega, 25, and Pena Jr., 24, announced their engagement in September. This is Vega's second marriage; she was married to producer Sean Covel from 2010 to 2012.
