Celebrity: Bono and The Edge (from U2)
Second job: Hotelier
The deets: Record a platinum album. Save Africa. Leave a chocolate on your pillow? Seems like U2's Bono doesn't feel busy enough touring arenas worldwide and regularly meeting with world leaders, so he took up a second job. Along with bandmate The Edge, he bought a hotel as well. The pair own The Clarence, a "premiere boutique hotel" along Dublin's River Liffey, which was built in 1852 and had fallen into disrepair by the 1970s. It attracted struggling artists and musicians, such as the not-yet-famous pair of Irish rockers. In 1992, they purchased the hotel and transformed it from two-star accommodations to five-star ones. But being businessmen doesn't mean they forgot their roots, as they proved by supporting their business the best way they know how -- by giving an intimate public performance of hits such as "Beautiful Day" and others on the hotel's roof.
