The boy band star and Strictly Come Dancing winner Louis headed to Ibiza with Aston's close friend and 2010 Big Brother finalist JJ Bird.
The friends have spent their time partying at luxury venue and celebrity hotspot, Ocean Beach Ibiza, in San Antonio.
Aston, who is holidaying without his JLS band mates, has been sharing plenty of photos and videos on Instagram and clearly isn't shy of flaunting his six pack!
The 25-year-old posed topless wearing just a red cap and blue floral shorts as he showed off his tattoo collection. Meanwhile, Louis posed in black pants, a necklace and a white cap.
Aston said last night (6 August): "Loving life a bit to much right now."
Apart from parties at Ocean Beach Ibiza, the boys also watched David Guetta perform his dance classics at popular nightspot Ushuaia and have pretty much spent the rest of their time soaking up the sun!
Aston touched down in Ibiza days after performing a charity gig with his JLS bandmates in Ireland and it seems as though he has been keen to unwind.
Before leaving, he had tweeted: "Actually a holiday now and no work... Oh the carnage!"
JLS will split up as a group towards the end of the year with a farewell tour. After their charity concert last week (1 August), Aston tweeted: "Gotta love Ireland... Gotta love JLSters full stop! Support is like no other! Tour will be emotional BUT will be the BEST time of our lives."
Plenty of stars have been partying in Ibiza in the past month including Tulisa and TOWIE's Lauren Pope, Jessica Wright and Joey Essex.
