Selena Gomez 'will stand by Justin Bieber'
Mariah Yeater filed a lawsuit earlier this month claiming that Bieber got her pregnant after a backstage romp at one of his concerts in October 2010.
Gomez is now planning to accompany Bieber to his work commitments whenever possible as a public sign of solidarity, according to the Sunday Mirror.
A source said: "Selena just wants the world to know she is 100 percent behind Justin. They both have very busy careers but she is planning to be with him as much as she can. The whole saga has brought them closer together."
The pair were said to be "openly kissing" and "very lovey-dovey" during a visit to Kiss FM yesterday, where Bieber was promoting his new album Under the Mistletoe.
A representative for Gomez previously insisted that the couple have not split over the paternity claims.
