The couple attended JLS's Marvin Humes and The Saturdays star Rochelle Wiseman's wedding at the weekend (July 28).
Speaking to The Sun, a friend said: "Liam and Danielle are already talking about serious commitment. He's got it all worked out already - he's really mature for his age.
"The boys were joking he would be next at Marv and Rochelle's wedding - and he didn't deny it."
