The MILF$ hitmaker opted for a rock chick look when it came to the rest of her ensemble, teaming a Moschino leather baker boy cap with baggy matching trousers. 

With a chunky black and gold leather Chanel belt to accentuate her tiny waist, she added a little more glitz with sparkling gold stilettos and a small leather shoulder bag.

Josh, 43, who stars in the film as pitcher Bill 'Spaceman' Lee, complemented his wife's leather look with a black leather jacket, but stopped short of the matching leather trousers opting for a pair of black jeans instead.

With black and white Adidas trainers and a black cotton T-shirt, the actor showed off an impressive tan, and looked relaxed and jovial as he posed on the red carpet.

Earlier in the day, the happy couple were able to bring along their little son, three-year-old Axl to a baseball game to promote the film.

With the sun shining, they were able to  spend some time on the pitch, with Josh showing his little lad some tips and tricks of the game.

The cute trio were in attendance for the Los Angeles Dodgers baseball game against the Boston Red Sox.

Up your style game in Fergie's Saint Laurent T-shirt

Fergie and her family have got real star quality.

And if you need any proof, just take a look at Fergie's red, white and blue star print t-shirt! It's by Saint Laurent, and when teamed with a pair of denim shorts and ankle boots, she knocked it out of the park when she attended an LA Dodgers game over the weekend.

Celestial-inspired prints have been a big trend in recent seasons, but rather than going for a dress or sneakers, why not splash out on a wear with anything t-shirt? At $490 it's still a little on the pricey side but it's definitely one of the more affordable ways to get some Saint Laurent in your wardrobe. Click the link (right) to buy it now at Farfetch, then tuck it into a leather skirt, or dress it down with distressed jeans.

Alternatively, show them you're a star in one of the printed options we've got lined up for you in the edit below. This Scotch & Soda version will do the trick!
