Long-time couple Kate Upton and Justin Verlander were recently spotted spending a romantic vacation in Cancun Mexico.

The on-again off-again couple were photographed by several witnesses who sent the images to different news agencies. They were all smiles as they had their skin tanned under the heat of the Mexican sun. Upton wore a blue floral-printed bikini while her man Verlander looked cool in his red swimming trunks.

It looked like they were having the time of their lives despite their already obvious sun burns. Upton was photographed looking a bit awry after she read a book by the ocean. She starts moving around hoping to find the perfect position to continue her sun-bathing while she enjoys a good book beside her boyfriend.

Eyewitnesses told E! News that they were "very loved up and enjoyed being with each other," an eyewitness said. Break-up rumors are definitely slammed as the couple looked far from strained.

Upton and Verlander started dating back in 2012 and were reported to split in 2013 after being seen on another romantic vacation in the Caribbean. The sports cover girl then dated 'Dancing With the Stars' dancer Maksim Chmerkovskiy for six months then got back together with her current beau and Detroit Tigers pitcher, Verlander.

It would seem that they are happier than ever. According to reports, despite Upton's hectic schedule, she makes sure that she has time for her personal life. For now, it is quite clear that the bombshell beauty is in a relationship with the hunk pitcher and all the best is hoped for the couple to continue to stay together.
