Because a five-bedroom, 9,200-square-foot home just isn't big enough for their growing family, Adam Levine and Behati Prinsloo are already moving out of their new Los Angeles mansion - yeah, the one they purchased around four months ago.

The Maroon 5 frontman and his (pregnant) supermodel wife snagged the French Regency-style estate in the ritzy Holmby Hills area for $18 million this past August and have now put it back on the market for $900,000 more. If the listing photos are any indication, the sprawling home was in dire need of some updates. Perhaps the higher price tag proves that they've given the place a modern makeover?

Nevertheless, real estate does not seem to be the couple's strong suit, seeing as the home they've been trying to unload in Beverly Hills has gotten a price cut and still won't sell. Better luck with these digs, you two!
