As previously reported, just one month before their twins are due, the couple, who originally married in February 2011, renewed their vows at the Little Church of the West in Las Vegas.
"Kayte is just absolutely miserable because she feels so lonely and isolated," a source close to the situation tells RadarOnline.com. "She and Kelsey are living in Chicago right now because he is filming his television series, Boss. Kayte has absolutely no friends and no support network around her. Kayte is alone most of the day while Kelsey is filming and at their recent baby shower for the twins all of the guests were Kelsey's fellow cast members and crew from the show. Kayte didn't have any of her friends at the shower because they are all in England. It's been a very rough pregnancy for her because she is pregnant with twins. Kayte is hoping that once the babies are born she won't feel so alone."
The 57-year-old sitcom star got Kayte's name tattooed in Chicago recently. "This is his first tattoo and it appears that he is trying to be someone he isn't for his new wife. It's sad that Kelsey felt he had to get a tattoo to prove his love for Kayte and then to post it to Twitter!," a source previously told RadarOnline.com.
Meanwhile, Kelsey has put his former home that he shared with ex-wife Camille Grammer on the market for a whopping $18,000,000! He and Kayte have downsized to a Mediterranean-style $6.5 million mansion in Malibu.
