Now that the Royal Sister is officially back on the market, many prominent figures are coming up as possible replacements for her long-time ex-lover, Alex Loudon.

According to a report, the younger sister of the Duchess likes her men with "well-built" physiques. Here are some famous bachelors that may very well be choices for Pippa:

1. Justin Timberlake

The ex-boyband member's crush on Pippa is no secret at all. Timberlake has professed his "obsession" on the Royal sister in a statement, and with his talent and gym-perfect built; it might be no surprise if the singer-slash-actor buys a ticket to London to meet Pippa.

2. Ryan Gosling

The "Drive" actor is one of the most in-demand Hollywood stars of today. Not only does he have a pure talent in acting, but Gosling is also known for his romantic ways. With past lovers like his "The Notebook" star Rachel McAdams, it is sure that Gosling can treat the Royal Sister like a princess of her own.

3. Prince Harry

There are rumors that Pippa's break-up with her banker ex was caused by a jealousy that sparked after the Royal Wedding. Pippa and Harry have been seen lunching out several times, though the pair insisted they were "just friends". If Pippa was to date Prince Harry, there's a huge chance she will also get into the Royal Family, just like the way her famous sister did.

4. Paolo Nutini

The Scottish singer is not only young and attractive, but he is also talented and has a boy-next-door appeal that any single woman would fall for. Famous for his melancholic-yet-brassy voice and songs, Nutini has a huge following in the international platform. Fans would surely adore seeing Pippa get serenaded by this singer. It was also said that the Royal Couple will move to Scotland in 2013, and if Nutini courts Pippa, it would be amusing to see her tag along with her sister to see this Scottish heartthrob. Watch a video of Nutini back in 2006 below:

5. Matt Smith

Famous for his starring role in the British hit series "Dr. Who," Matt Smith is a top choice for Pippa's pool of bachelors. Aside from his successful television acting career, Smith is also famous for his stage and theater career, a passion he can share with the younger sister of the Duchess.
