The MCFly guitarist and singer exchanged vows with the former Miss England beauty at a ceremony held in North Yorkshire, England, becoming the third member of the band to wed.
Bandmates Tom Fletcher, Harry Judd and Dougie Poynter were all in attendance, with Poynter's pop star girlfriend Ellie Goulding also a guest.
Other attendees included MCBusted members James Bourne and Matt Willis.
Jones and Horsley announced their engagement in July last year (13) when the musician shared a picture of himself and his partner showing off her engagement ring on Twitter.com.
The couple began dating in 2009 following Jones' split from Horsley's Miss England successor Laura Coleman.
