Hollywood actress Scarlett Johansson Covers Vogue's May Issue while Spanish actress Penelope Cruz Covers Harper's Bazaar's May Issue

It's about time someone gave Scarlett Johansson the chance to channel some old Hollywood glamour. US Vogue editor Anna Wintour, well-known for her keen sense of the unexpected, tapped up-and-coming fashion photographer Mario Testino to shoot the actress for the glossy's May 2012 cover.

Johansson was not the only one making it to the cover of a top fashion magazine in May. Spanish actress Penelope Cruz joins her as she covers the May issue of Harper's Bazaar.

Styled with Grace Kelly curls and glossy lips, Johansson embodies the fantasy of the screen siren of yore. I've long suspected that the A-lister could pull off this kind of classic pose and polished style, and it's gratifying to see both Vogue and ScarJo take a risk that paid off.

An editorial spread accompanies the cover image. Because everyone knows that the ultimate retro glam accessory is a leopard, the oversized feline predator stays close to Johansson's side from photograph to photograph. The actress' Avengers co-star, Mark Ruffalo, joins her for the photo series, because every leading lady needs the company of a dashing cad lad.

Penelope Cruz, on the other hand, is not the celebrity who likes to tell everybody about what she feels, but she decided not to hide that she has a crush on Meryl Streep. Cruz, who covers Harper's Bazaar US May 2012 issue wearing a sparkling low neck dress, told the magazine about how much she enjoyed a partially nude magazine shoot with her idol Meryl Streep.

The Harper's Bazaar's cover girl said that it was Streep who inspired her to become an actress: "As soon as she got to the set, I had to sit topless on top of her. It was the most interesting love scene I have ever done. When I first started watching movies and I saw Meryl's work, that's when I became obsessed with acting. Maybe I'll make one movie a year, maybe two, but it's not going to be more than that because I have other priorities now."
