"Cheryl was taken aback by the gesture. She genuinely wasn't expecting it and was truly touched. It was an easy choice for Liam, he knew it was the right thing to do," a source said.
Things are said to be going positive for the couple after Cheryl won over the 22-year-old singer's parents Geoff and Karen at a recent family gathering, reported Contactmusic.
"Cheryl has completely won them over, and now they're both convinced she could be The One that Liam could finally settle down with. Karen is now convinced Cheryl is the perfect candidate to be Liam's wife," the source added.
