The Exes (2011)

S2E4 Baby Mama

Stuart's ex-wife allows him to have Chopin, the dog he lost in their divorce, for a short visit. However, a mix-up occurs when Phil, after a spontaneous night with a fellow dog owner, mistakenly swaps Chopin for a similar-looking pooch. Meanwhile, Holly grows increasingly convinced that Eden is involved with their married boss, Mr. Hubner (James Morrison), especially after she learns that Eden is expecting a baby.
