Of course not.
And I doubt that she can no longer dance like she used to. Just because someone doesn't showcase their talents doesn't mean that they don't have them.
She's a mediocre singer (always has been) but she's still talented in other aspects like being a good song writer, plays piano and she's very creative. Britney has created the concept to the majority of her videos with 'Criminal' being the most recent. She's always been very hands on in her career, more than people realize or simply give her credit for.
The problem is DANCING was always seen as Britney's main talent, and since that quality has greatly diminished it makes one question her level of talent. And rightfully so.
