Guy drama seems to follow Bachelor winner Vienna Girardi
. After a nasty split
from her ex-fiancé Jake Pavelka last month
, she's already encountered problems with her reported rebound guy Gregory Michael
"At first, Gregory thought Vienna seemed cool as a friend," a close pal of the actor tells PEOPLE. "But then he quickly realized she told lies and was bad for his image. He started ignoring her, but she won't leave him alone."
Signs of trouble between the two friends began earlier this month when they reportedly exchanged harsh words during an unexpected run-in at Hollywood's MyStudio nightclub. Michael, 29, apparently showed interest in another woman, and Girardi wasn't having it. Michael's pal, who has seen texts Girardi, 24, has sent as recently as last week, says the Bachelor
winner should have taken a hint by now.
"He seriously never responds to her," the source says. "He stopped texting after the night she showed up at MyStudio. She has sent him recent texts that say things like, 'I am sorry. I am who I am. I hate that I can't do anything normal. You have no idea how much I hate all of this. I'm sorry I got you involved.'"
But apologies won't get Girardi anywhere with Michael. "Gregory has absolutely no intentions of having further interactions with Vienna," the source says. "His manager and agent have both voiced their concern over this situation taking focus away from his acting career."
As for Michael's part, "no comment," he says. "I just want to move forward and go on with my career."
"Vienna has no idea where this is coming from," a rep for Girardi says. "She is not looking for any sort of relationship or friendship from him, but wishes him all the best." --Dahvi Shira
