ONE DIRECTION star HARRY STYLES was reunited with his ex-girlfriend CAROLINE FLACK during his birthday party in London on Thursday night (31Jan13).
The singer celebrates his 19th birthday on Friday (01Feb13) and he marked the occasion by taking a group of his friends for a night out in the British capital on the eve of his big day.
Styles and his pals, including actor James Corden, enjoyed dinner at a Mexican restaurant before going on to party at the Groucho Club venue, where he met up with his former girlfriend Flack.
Styles split from the 33-year-old TV presenter last year (12) after a three-month relationship, and he was recently rumored to have ended his latest romance with U.S. pop star Taylor Swift.
In a post on Twitter.com on Friday (01Feb13), Styles acknowledged his birthday, writing, "I feel olllllllllllldddddddddddd (sic)."
