Pop star Lady Gaga, who recently said that she has no time for love, is reportedly dating her best friend Matthew Williams.

The 'Poker Face' hitmaker is said to have grown increasingly close to her style collaborator Matthew Williams in recent 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 more than a year, but called it off when mixing work and love became too difficult," a source 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 love 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 source added.
