The TV hunk was recently spotted chatting up Lauren Conrad at the HTC Status phone launch on July 20.
The two shared a table at the even, and even exchanged numbers at night’s end. While a Conrad insider says “they are friends and have known each other forever”, a witness is more affirmative: “She was into him, and vice versa. They went to a club afterward.”
Yet Haynes – who appeared on two episodes of The Hills when Conrad interned at Teen Vogue – could end up heartbroken. A source says Conrad still speaks every day with ex Kyle Howard, 33 (the two broke up after three years, in May). Says the insider, “They may get back together.”
