But now Dave Haywood is in a twosome of his own – he's getting serious with girlfriend Kelli Cashiola, his rep tells PEOPLE.
The pair have been dating for six months, but have been friends for about five years.
"I feel so lucky that our long friendship has grown into this relationship," Haywood, 29, says. "We are totally comfortable and ourselves with each other."
Cashiola, 29, who works in marketing at Warner Music Group, recently joined her musician boyfriend for a weekend in Paris while the band was overseas promoting their third album, Own the Night
No word on whether Haywood will go down the road bandmates Hillary Scott, who's engaged
to drummer Chris Tyrrell, and Charles Kelley, who's married to
Cassie McConnell, have gone down.
