Preteen screen queens were all the rage in the early aughts, and Hilary Duff and Lindsay Lohan were among the biggest names of the sensational generation.
Duff was both a small screen star and a radio regular, while Lohan was quickly working her way up the Hollywood movie ladder, but things got messy for both young women when it came to Nick Carter.
Love triangles are rarely kept a secret in Hollywood, but there are a few that flew way under the public's radar.

Everyone knows about the legendary love triangle of Angelina Jolie, Brad Pitt, and his ex-wife Jennifer Aniston, but before that, the actress was at the center of another Hollywood breakup.

director Rupert Sanders (mostly because they were photographed mid-smooch by the paparazzi), but some of Pattinson's own potential dalliances were made a little less mainstream.

Thornton himself has admitted that the press attention that followed their "whirlwind" romance "had some basis in fact." Jolie and Thornton divorced in 2003, reportedly due to his disinterest in having more children, despite their joint announcement of adopting of her first son Maddox from Cambodia.
Jolie received full custody of the child, and he was eventually adopted by Brad Pitt, with whom she now has six kids.
