He and his pregnant fiancée Nicole Tuck are the latest music industry stars to check out 234 E. 23rd St.’s penthouse, which Adele’s reps recently inquired about as she was looking for a short-term rental to stay in while she was in town.

We have first-time photos of the renovated four-bedroom duplex, which will soon hit the market for $12.5 million.

Building amenities include a gym, library with a pool table, a garden, and a rooftop space with an outdoor kitchen.
