The sighting comes after UsWeekly reported that Riley and Ben tied the knot in the romantic setting of Napa Valley's vineyards in California. 

The guests included Kristen Stewart, Zoe Kravitz, Cara Delevingne, the bride's Mad Max: Fury Road costars Abbey Lee and Courtney Eaton, and Keough's ex-boyfriend Tobias Jesso Jr.

Riley's mother is singer Lisa Marie Presley, 47, who was married to Michael Jackson from 1994 to 1996.

Riley and Ben met when they were filming Mad Max: Fury Road in 2012 in Namibia with Charlize Theron and Tom Hardy (the movie will come out in May).

In August Smith-Petersen - who works as a stuntman - confirmed the couple were engaged. 

'So that happened,' he captioned a Facebook photo of her diamond engagement ring. 

'So happy for them. They joked about having a dog baby together now and how it was just a matter of time until they made it official,' a source told UsWeekly several months ago.

'They're very serious,' a second insider added. 'They're perfect for each other. Great people.'

This is the first marriage for Keough. She was previously engaged to Alex Pettyfer in March 2012. 

Keough got her start as a model and appeared on the cover of Vogue with her mother Lisa Marie and grandmother Priscilla Presley in 2004.

She then started working in films including 2010's The Runaways with Stewart, and 2012's Magic Mike with Channing Tatum.

The brunette has been filming Dixieland - about a 20-year-old man who tries to make a fresh start after leaving prison - with Faith Hill and Steve Earle.
