Oritse Williams cried when Marvin Humes told him he'd proposed to Rochelle Wiseman
The 25-year-old pop star got emotional when his JLS bandmate revealed he had asked the Saturdays singer to be his wife.
2 June 2012 Oritse admitted said: "I had a little tear when he told me he'd proposed."
Marvin and Rochelle are due to tie the knot in July and despite being single, Oritse and fellow JLS singer Aston Merrygold are both confident of having a date to take to the wedding because of their superstar status.
Aston explained to new! magazine: "We're in a boy band and if you can't bag a date to a wedding, you've got serious problems."
Oritse has recently been hitting the gym hard in a bid to tone his body, and his new-look muscles have attracted "a lot" of his ex-girlfriends.
He explained: "Put it this way, a lot of ex-girlfriends have come out of the woodwork. It's an interesting situation.
"I wanted to prove to our fans that I'm just like them. I'm a pop star but I have my issues too.
"I never weighed myself, I just kept a picture diary. A picture never lies!"
The fourth member of JLS, J.B. Gill, is in a relationship with Chloe Tangney.
