(Cover) - EN Showbiz - One Direction's Louis Tomlinson is "as serious as you can get" about his girlfriend.

The British singer and Eleanor Calder recently had to deny engagement reports after she was spotted wearing a ring on her wedding finger.

They have been dating for less than a year but are apparently deeply in love.

"For people so young, they're as serious as you can get, despite only being together a short time. They always get teased by friends and family members about when they're going to set a date," a source told Heat magazine.

Eleanor is a student and Louis has previously said her everyday life helps him remain grounded.

The 20-year-old singer is a big hit with his girlfriend's family too.

"Louis gets on well with Eleanor's mom - he's always trying to get in her good books and she's quick cheeky to him," the insider added. "And Eleanor loves Louis' mother." (C) Cover Media
