Amanda Seyfried, 'Lovelace' and 'Chloe' movie star, showed sideboob during her Givenchy heels, Gucci dress near wardrobe malfunction at her Los Angeles premiere on Monday, according to Hollywood Life.

The actress, 27, was photographed without a bra and narrowly avoided revealing her private parts in a short black mini dress with sky-scraping, open toe heels, reported HL.

"[The actress] may have gotten a little too comfortable playing her on-screen character, [adult film] star Linda Lovelace," said an HL intern, "as she opted for a very sexy look on the red carpet."

Her designer halter top frock was completely covered in bronze and gold embellishments. It draped her body near perfectly, with a high neckline and plunging sides, which, of course, gave a peek-a-boo look at her sideboob.

Luckily, the starlet's dress stayed in place though she still revealed a noticeable amount of skin.

The ensemble was very befitting for her hypersexualized character, who has inspired Seyfried to be more open and risque with her red carpet looks. The starlet gives some glam mixed in with the sex appeal, too.

She paired the racy dress with Graziels Gems earrings and stunning eye bronze smokey-eye makeup, which complemented her outfit and made her big eyes pop.
