The marriage plans of former vice presidential candidate Sarah Palin's daughter have been thrown into jeopardy after reports her fiance's ex-girlfriend is pregnant with his child.
Bristol Palin, 19, announced plans to wed Levi Johnston last month after their first engagement in December 2008 was called off.
But a report from tabloid newspaper the National Enquirier claimed Mr Johnston, 20, was expecting another baby with ex-girlfriend Lanesia Garcia, conceived during his split with Ms Palin.
The news has reportedly prompted Ms Palin to call off the wedding but a representative from the Alaska family said "no official decision had been made".
The couple found themselves thrust into the public eye when former Alaska governor Sarah Palin was named as John McCain's running mate in the 2008 presidential election.
Shortly after Governor Palin received the nomination, it was revealed Ms Palin was expecting a child with Mr Johnston.
The couple announced their engagement during the election campaign but called off the marriage two weeks after their son Tripp was born.
In September last year Mr Johnston gave a tell-all interview with Vanity Fair giving a highly unflattering critique of Governor Palin.
He has since said some of the things in the interview were "not completely true".
