It only took two words for Ava Phillippe to present her stance on the debate whether her boyfriend, Owen Mahoney, looks like her father, Ryan Phillippe.

A friend of the 19-year-old stood up for her on Instagram on Monday, writing, "He does not look like your dad." To which Ava responded, "Big thx."

The debate started when Ava posted a photo of herself with Mahoney to her social media account on Sunday. It didn't take long for people to take notice of a slight resemblance to the teen's father.

One Instagram user (@wutangclannnnn88) commented, "He looks so much like your dad omg." Meanwhile, another user (@kylekohen) disagreed, stating, "looks nothing like Ryan omg leave the poor girl alone."
