Jay-Z and Beyonce have both pledged their allegiance to Barack Obama in the run-up to tonight's US presidential election.
The most powerful couple in music are hoping to sway floating American voters towards the democratic candidate.
Beyonce posted a picture on her tumblr site that shows a letter of support she sent to President Obama.
The Destiny's Child singer spoke of her "respect and adoration" for the current president, and said she trusted Obama to get the US to 'where it needs to be'.
Meanwhile husband, Jay-Z, performed at Obama's rally in the 'battleground' state of Ohio last night.
The revelation of Beyonce's letter comes after she also sent a written message highlighting 'how proud' she was of the country's first lady, Michelle Obama last April.
She also stepped out last month wearing a pair of gold earrings with Obama's name engraved into them.

Jay-Z gave his hit '99 Problems' a political twist in an effort to steer voters towards Obama at the expense of republican candidate, Mitt Romney.
He changed the chorus of the track to "I got 99 problems but Mitt ain't one" as he performed in the 15,000 capacity Nationwide Arena.
And the New York rapper and his wife were not the only music giants to show their support. Jay-Z was also joined by 'Born in the USA' stadium-filler, Bruce Springsteen.
The success of the event in Ohio was much needed for Obama, after a special event was put on in the 'undecided' state on Saturday, which featured a performance from Stevie Wonder.
The poor organisation of the free show meant that only 200 people turned up to watch the 'Superstition' star, with many claiming they did not find out until half an hour before the start of the set.
