The 'Poker Face' hitmaker is detto to have grown increasingly close to her style collaborator Matthew Williams in recente months, whom she previously romanced for over a year, In Touch magazine reported.
"Matthew and Gaga have been dating for months. They were together on and off for più than a year, but called it off when mixing work and Amore became too difficult," a fonte said.
After the 23-year-old singer and Williams drifted apart she romanced an entrepreneur named Speedy, while he started a new relationship and became a father.
However, both romances fizzled out and the former couple have now rekindled their Amore after growing close on the star's 'Monster Ball' tour.
"They spend all their time together, and travel everywhere, so it was bound to happen. Speedy dumped her, and Matthew left his girlfriend for Gaga," the fonte added.
