Liam Hemsworth was spotted leaving his New York City hotel alone this week and Miley Cyrus has been busy promoting her music around the world, leaving PerezHilton.com to believe the couple might be too busy for sex.

"Are Mileybird and her beau TOO BUSY for love, and all which it entails?" PerezHilton.com writes.

"We know Liam's sched is packed right now, promoting his new movie, Paranoia, in New York, which comes out later this month, then prepping for the release of The Hunger Games: Catching Fire, which will be out this Fall, AND gearing up to shoot the following HG movie, Mockingjay Part I in just a few weeks!"

Miley Cyrus and Liam Hemsworth were also both spotted in Los Angeles last weekend, but the couple was not together - the "Hunger Games" star was catching a flight at LAX while the "We Can't Stop" star was seen strolling at an outing.

The couple has been getting attention after Miley Cyrus' little sister, Noah, revealed they have no wedding plans.

However, Noah also revealed she might be planning the event for Miley Cyrus and Liam Hemsworth since the couple has been busy promoting their newest endeavors while trying to avoid speculation about a split in their relationship.
