'Busting' Pune city

BBC reports that Brad Pitt and Angelina Jolie are in Pune.

The article talks about Pune as "busting Western city". I have heard of 'bustling' cities, I have heard of cities 'bursting' at the seams, but a 'busting' city? Is that a veiled reference to La Jolie's appearance as Lara Croft in the Tomb Raider movies?
