Singer Jennifer Hudson has reportedly slammed Jessica Simpson over her "joke" weight loss.
The Dreamgirls actress, having transformed her body shape completely using the Weight Watchers plan, probably thought she was passing the torch onto Simpson when she signed on, but came away less than impressed with the outcome on the Texan singer.
According to a source, a fellow Weight Watchers pitchwoman said:
''Jennifer is frustrated with Jess and how she's handled her weight loss fiasco. She thinks Jess' stab at dieting has been a colossal jokes. Jen said that Jessica still looks fat despite an enormous $4 million incentive to lose weight.''
It seems the former American Idol singer's annoyance stems from her frequent efforts to help new mum Jessica shed the weight.
According to one source, the 31-year-old Chicago-native even phoned Jessica multiple times to offer pep talks and tips, as well as even FedExing her diet diary as motivation.
''Jennifer thinks Jess has been lazy and not serious about getting fit,'' continued the insider. ''Jessica obviously didn't put in the work.''
And now Hudson has hit back, after she tweeted sultry lingerie snaps of her toned body and 80 lb weight loss - four days before Jessica's big reveal on Katie Couric's new talk show.
''She's written Jessica off as a total mess,'' reveals the source, ''Jennifer is definitely having the last laugh.''
