Taylor Swift has bought the web domain names TaylorSwift.porn and TaylorSwift.adult.

The addresses are part of a public sale by the Internet Corporation for Assigned Names and Numbers (ICANN).

The web domain names go on sale to the public on 1 June but some stars and companies are being given the opportunity to buy them ahead of then.

Microsoft Office has registered Office.porn and Office.adult. Domains can cost up to $2,500 (£1,674).

However, .porn and .adult are $99 (£66).

Richard Branson and Stringfellows are other names to have bought .adult and .porn domains, according to ICANN.

The American non-profit group expanded the number of generic top-level domains, or gTLDs, such as .com and .net in 2011.

There were 22 four years ago but now there are nearly 550 with new ones released every month.

The group says different endings to web addresses can help users arrive at their destination quicker because they know what they're getting.

It also says websites ending in .porn or .adult are easier for parents to monitor and block.

Another domain name being released in June is .sucks.

In January Taylor Swift applied to trademark five phrases from her latest album 1989 with the US government.

"Party like it's 1989", "this sick beat", "cause we never go out of style", "could show you incredible things" and "nice to meet you, where you been?" were all apparently registered by the singer with the United States Patent and Trademark Office.
