Reunited ... and it feels so good.

Newly single Audrina Patridge bumped into Glee's Mark Salling at Katy Perry's post-MTV Movie Awards bash at John Terzian and Brian Toll's Las Palmas in Hollywood.

With a drink in her hand, Patridge ran over and gave Salling a hug -- and the two posed for a series of photos together. Check out more party pics

Patridge couldn't help but contain her excitement at the party: "At katy perry's vma after party:)!!!" she Twittered.

She first met Salling at an Us Weekly Hot Hollywood party in Los Angeles last year, where they spent 45 minutes flirting and laughing.
