12:08 PM PT -- Jenny Sushe -- along with Allred -- just addressed the media and said the boxer not only kissed her without consent, he also groped her butt after the interview.

After the interview, Sushe claims the boxer asked her to remove the kiss from the interview because he knew how it would play out in public, but she refused.

In a letter to the California State Athletic Commission, Allred says, "We hereby request that the commission conduct an immediate investigation into the serious allegations."

"We request that Mr. Pulov's boxing license be suspended."

The female reporter who was suddenly kissed by a boxer she was interviewing AFTER his fight has lawyered up ... hiring Gloria Allred to go after his ass.

The video went viral over the weekend -- showing 37-year-old Bulgarian heavyweight Kubrat Pulev planting a kiss on the mouth of reporter Jenny Sushe during a post-fight media session.

Following the incident, Pulev said the Vegas Sports Daily reporter is a "friend of mine" -- and he passed the whole thing off as no big deal.

"On the video, after our kiss, we both laughed about it and thanked each other," Pulev said ..."There really is nothing more to this."

Well, clearly Sushe thinks it's a big deal ... she's hired Allred and she's planning to take legal action against the boxer.

In fact, in classic Allred form ... the attorney is holding a press conference Thursday to announce the plan of attack.
