Justin Bieber is growing up; even if the claims that he'd fathered a child with 20 year-old Mariah Yeater look like coming to nothing, the 17 year-old is becoming increasingly touchy feely in public with girlfriend Selena Gomez and the star was once again in flirtatious mood as he was snapped groping his other half's bum during a promotional trip to Washington DC.
Bieber was in the US capital to perform a special show in front of President Barack Obama, where he performed alongside other stars including Cee Lo Green and Jennifer Hudson; the UK's Daily Mail newspaper reports that the singer ditched his usual casual attire in lieu of a white tuxedo to sing in front of the President before all attending joined the Obama family in singing carols.
Bieber and Gomez have been showing increasing affections towards each other the past few weeks, leading to rumours that they are set to get engaged - something the pair have both denied. Last week the couple were in Mexico for a wedding featuring one of Gomez' best friends and were seeing getting amorous then, lounging out by the pool at their hotel there in an array of clinches. With Bieber's paternity issues seemingly behind him, it looks like he has his full attentions back on his other half.
