Bachelor Matt Grant & Shayne Lamas call it quits

"We tried hard to make it work but we realized that we were both heading in different directions," the two said in a statement to PEOPLE. "We truly care about each other and will remain close friends."

Neither would elaborate.

Grant, 27, and Lamas, 22, have been plagued with reports of trouble since their televised engagement on ABC's The Bachelor: London Calling in May.

One month later Grant told PEOPLE that he had moved out of Lamas's Century City condominium, citing a need for "space."
