Guess who is back in the party circuit - its none other than the Bengali bombshell Riya Sen and she's looking killer and raring to go! Riya is back from a short vacation from Bangkok with her family and is looking more stunning than ever. Generally people gain weight when they go for their vacation but this actress has maintained her svelte figure and surprisingly has lost oodles of weight!

In fact, Riya was cynosure of all eyes recently at Subhash Ghai's party. Though she made a late entry because of her shoot, she looked ravishing and turned the heads of one and all present! She even received a galore of compliments from various people including director duo Abbas-Mastan and Comedy King David Dhawan. With her recent weight loss and the all new look she was without doubt the center of attraction!

Looks like Riya is one lady who knows how to have a 'healthy' vacation!!!
