House

They might be the best couple on TV, but someone will get between House and Wilson on a future episode of House.

Sasha Alexander - best known for playing Agent Todd on 48 episodes of NCIS from 2003-2005 - will appear on one installment of the Fox hit later this season.

According to Entertainment Weekly, the actress will guest star as the neighbor of this adorable twosome when they move into new digs. Both characters will crush on the beauty, but don't worry, fans.

Nothing can do long-term damage to our favorite television bromance.
