Spotted: Dianna Agron and Alex Pettyfer kissing

Glee actress Dianna Agron has reportedly been spotted engaging in a very public display of affection with Alex Pettyfer.

According to E!, the couple enjoyed lunch al fresco the other day in Beverly Hills, but they surprised fellow diners with an impromptu makeout session.

Apparently after they finished eating, Dianna, 24, and Alex, 20, skipped dessert and instead opted for some major PDA.

An eye witness told the site: “They were full-on tonguing,” and added that once Dianna had finished “sucking face with her boyfriend,” the couple left the eatery.
