The 26-year-old actor was overheard introducing Miro to a fellow patron as his 'girlfriend', reported E!Online.
The new couple were most recently snapped by shutterbugs arriving in Copenhagen, Denmark, over the weekend, where they attempted to stay incognito by wearing hoodies, hats and dark shades.
Prior to their travels, the actor and Miro were seen attending a Dodgers game together last month where they cosied up and cheered on the boys in blue.
According to her LinkedIn profile, Miro lives in Los Angeles and works in business development for a digital content and media company. She speaks French and was a Junior Olympic gymnastics state champion in May 2000.
