Rakul's fitness obsession costing her charm?

In films as different as 'Dhruva' and 'Rarandoi Veduka Chuddam', Rakul Preet Singh was so charming. She performed strong roles in films like NTR's 'Nannaku Prematho' too. Besides looking thoroughly confident, she was charming in these films.
Looks like Rakul is losing her charm at a time when Tollywood is not signing her up for many movies. But for the Naga Chaitanya-Bobby movie, she has no Telugu films on hand. In Krish-Balakrishna's 'NTR', she will be seen in a cameo as late Sridevi.
The 28-year-old actress is doing 'NGK' opposite Surya, a film with Karthi, another with Siva Karthikeyan in Tamil, and a Hindi film. But in her hurry to look leaner and better, Rakul is fast losing her old charm. The glow is visibly fading away on her once-tempting face.
All of this is apparently happening because of her extreme love for fitness! Ironically, she is a fitness freak who also owns a gym franchise in Hyderabad and Vizag.
