Jerry O'Connell shows off his toned physique in yet more skimpy swimwear

He must be getting used to his skimpy wardrobe by now.

Jerry O'Connell spent yet another day lounging in Speedos on the Los Angeles set of his new sitcom We Are Men, and was looking impresively sleek and toned.

The 39-year-old actor recently told a panel at the Television Critics Association that he has his wife Rebecca Romijn to thank for giving him some handy advice on how to get his body Speedo-ready.

Green day: Jerry O'Connell slipped into yet another pair of tiny Speedos on Monday on the set of his new CBS TV show We Are Men

Jerry, who is most famous for his role as an overweight teen in the 80's film Stand By Me, looked particularly tidy in the green swimming attire.

His tanned body was rather sleek and shiny; he could have passed for a swimwear model as he paraded around his new and improved look.

The actor shot scenes that involved him lounging around on comfortable looking deck chairs with his co-stars Kal Penn and Tony Shalhoub.

Jerry must surely have been relieved when 'cut' was called and he was able to slip into a nearby pair of track pants.

The star spoke about his new role during the TCA's last week, saying: 'It is probably the most nerve-wracking job for me to put those on every morning.'

'We're a couple episodes in and I'm in the Speedo continually,' he said.

'I have joined a gym and I've started drinking light beer. I don't know how guys like Michael Phelps do it all the time,' Jerry continued.

And the actor referenced his Stand By Me days, adding: 'I was known as the fat guy from Stand By Me... I guess I'll be known as Speedo guy.'

Jerry gave his wife, actress Rebecca Romijin, credit for throwing him a word or two of advice in the leadup to his new role.

These, really? Jerry appeared somewhat disturbed by the wardrobe department for his TV series in a Twitter snap uploaded by his co-star Kal Penn

'My wife's advice was, 'Go get a tan, do some pushups and maybe do some Pilates.'

Hilariously, Rebecca has recently joined Twitter and may have already created a new photo-bomb meme incorporating dads in Speedos.

Last week, the actress posted a happy snap of the couple's smiling twin daughters, Dolly and Charlie, with Jerry lurking in the background... in his Speedos.

'Daddy photo-bomb!' she said as she uploaded the funny snap that slyly showed off her trim and terrific husband.
