Did he really mean this? If sources are believed, yes. Naga Chaitanya suggested Simbhu to stay away from his debut movie heroine Karthika. 
Karthika, daughter of yesteryear heroine Radha paired opposite Naga Chaitnaya in 'Josh' which got lukewarm response at box office.
It is learnt that Naga Chaitanya suggested Simbhu not to pair with Karthika. Additionally, Naga Chaitanya asked Simbhu to watch his debut movie ‘Josh’ and reconsider his decision. Simbhu took his advice seriously and watched ‘Josh’ and requested director to change the heroine. Simbhu who had even done a photo shoot for the movie ’Ko’ opted out just before the film’s first schedule as director not agreed. Now, director replaced Simbhu with other hero Jeeva and retained Karthika.
Simbu became close to Nag Chaitanya during the making Gautham Menon’s bilingual movie Vinnaithandi Varuvaayaa with Simbhu in Tamil and ‘Ye Maya Chesave’, with Naga Chaitanya in the Telugu version.
