When it comes to Tay-Tay's love life, one day you're in and the next you're out, so you can never be too sure.

Cashing in on Taylor Swift's latest unconfirmed relationship with actor Tom Hiddleston are several Taobao retailers who have started to sell "insurance" to the singer's fans or anyone interested in making a quick buck.

What exactly does the plan cover? Well, sellers have promised to pay double of what buyers pay when taking up the insurance if the couple were to break up.

According to Xinhua, punters have also started taking bets on the online marketplace to see if "HiddleSwift" will last at least a year. Bets start from 1 yuan ($0.15).

Xinhua reported that the Taylor Swift "breakup insurance" is not a one-off, citing that insurance packages for celeb couples such as Katy Perry and Orlando Bloom are also available for sale on the site.

Taobao is China's biggest online shopping site and is a treasure trove of all sorts of products ranging from clothing items to eccentric goods such as pee sticks for kids.

In November last year, Taobao's parent company, Alibaba, smashed sales records on China's Singles' Day -- the equivalent of Black Friday in the U.S. -- in 12 hours, making $9.3 billion in sales.
