Alex Assault victim Alex Welch seeing plastic surgeon and still waiting for apology from Demi Lovato

The nasty punch to her face caught her totally by surprise and she is still waiting for Demi Lovato to make ammends for her shocking behavior.

“To this day, I haven’t got an apolgoy. I’ve heard nothing,” the 21-year-old dancer Alex Welch told PEOPLE. “That’s sad if you think that person is your friend.”

Five weeks ago, after a concert, Demi got upset because she had gotten into trouble for her partying behavior and suspected that one of the dancers had snitched on her.

Walsh, who insists she did not tattle on the Disney Star, went on to say: “We were on the plane with the Joeses having this awesome time and I didn’t get a call or text from Demi or a ‘hey, you got a problem with me,’ nothing. And she walks up and punches me and literally waled away and got in her seat.”

The attack left the back-up dancer with a black eye and bruised cheek bone, but not any permanent damage, PEOPLE reports.

However, according to RadarOnline, Welch — who has hired Beverly Hills attorney Donal Karpel and might pursue litigation — had to receive emergency medical treatment following the incident, as well as further consultation from a cosmetic surgeon.

“After the attack, Alex had to get emergency treatment,” Karpel said. “She is now consulting a Beverly Hills ears, nose and throat plastic surgeon.”

The high-powered attorney also said that Welch intends to take Demi to court, although –as we reported yesterday — the star’s father is warning the the dancer not to sue his daughter. “She won’t win,” he told RadarOnline. “Demi has really good lawyers and so does Disney, this girl shouldn’t sue.”
