Jennifer Lawrence was completely in her element when she attended her best friend Laura Simpson's wedding in Florence, Italy, on May 27. After doing a little sightseeing in the city with her pal Aziz Ansari a day earlier, the X-Men: Apocalypse star was her usual funny self as she joked with the actor and fellow party guests at Laura's stunning reception. In addition to sipping on a few cocktails, Jen helped Laura, whom she famously took to the Oscars in 2014, with her dress and cracked a few of her trademark faces. Gotta love her!
