The caption reads: “WELL……WE HAVE DECIDED NOT TO BE A DUO ANYMORE!!!!!!! #Jan2016 #T3 #WeDidIt #BabyOnBoard.”
The two are seen holding Diet Coke cans together. Keifer has a “dad” can while Shawna holds up a “mom” one.
In a statement to E! News Tuesday, the Thompsons added, “We are overjoyed to announce that after 16 years of marriage, we are finally starting a family and are excited beyond words to begin this new journey into parenthood!”
The pair, who have won the Vocal Duo of the Year awards twice, have created hits like “Are You Gonna Kiss Me or Not” and “If I Didn’t Have You.”
Keifer told People, “We’ve been together for a long time and we’ve done a lot of things and we just really felt there was something missing. We love what we do, we love the music business, but we didn’t want to deprive ourselves of having a family.”
Shawna said the baby won’t slow down their touring. She exclaimed, “We’re going to need to turn one of the bunks into a crib and we’ll need a changing area. It’s going to be interesting.”
Keifer, 39, added, “We’re really, really excited. We’ve been together for a long time and we’ve done a lot of things, and we just really felt there was something missing. We love what we do, we love the music business, but we didn’t want to deprive ourselves of having a family.”
As for pregnancy cravings Shawna said, “I was eating strange combinations.”
“That’s before she even knew,” shared Keifer. “She was like, ‘I think I might need to go get a test because I just ate a cantaloupe followed by a pickle chaser.’ ”
Asked about baby names Keifer joked about the possibilities.
“I already got Thompson in there, so I said Shawna gets to pick the name as long as it’s not something crazy like these people in Hollywood do all the time. No Moonbeam for us!. Though I think it would be fun … maybe we should go with something really weird and random. Toothpaste Thompson. That is a great alliteration — and we are songwriters, you know.”
