Heidi Klum and her bodyguard/rumored boyfriend Martin Kirsten stepped out for a late lunch Tuesday at Joe's Stone Crab in Las Vegas.

"They were very affectionate throughout the meal," an onlooker tells PEOPLE.

The couple enjoyed oysters, stone crab, pan-roasted sweet corn and filet mignon.

Earlier this month, a friend of Klum's told PEOPLE that the relationship between the model-turned-mogul and Kirsten is "complicated" but that Kirsten is Klum's "no. 1 confidante."



While their relationship is yet to be publicly confirmed, during a recent appearance on Katie, Klum spoke fondly of Kirsten, explaining that he has "cared for our four children and helped us tremendously" since working for her over the past four years.
