Ava, whose father is actor Ryan Phillippe, looked to be having a blast with Arthur as they headed to Sketch Bar across the pond in London, England.
The 18-year-olds looked quite happy to be with one another on their way in, although their was no visible PDA shown on either end.
She looked London-chic in her plaid purple coat, whereas Arthur went the casual route for a fun night out.
Ava and Arthur also bumped into some famous friends prior to entering Sketch Bar that night! Knocked Up actress Leslie Mann was enjoying some quality time with her 20-year-old daughter Maude. They all looked absolutely elated to see one another.
Could both their mothers be responsible for setting these two up? According to Page Six, Arthur’s mother Mary McCartney, Paul’s daughter with first wife Linda McCartney, was spotted at Reese’s party for her film Home Again last year. Is this a budding relationship in the works for 2018 and possibly beyond?
