It's no lie: Kristen Bell is jealous of someone else's baby.

If you ask us, Kristen Bell and Dax Shepard's newborn baby daughter Lincoln is pretty darn adorable, but she thinks True Lies star Tom Arnold's new baby has upped the ante, according to Us Weekly.

"Tom Arnold, your baby is so much cuter than ours," Kristen tweeted on April 11. "Big deal. I can admit the facts."

Kristen starred with Tom Arnold in last year's action comedy Hit and Run.

Tom then responded to say that her baby is not too shabby either.

"But yours is so much more mature," the 54-year-old Tom responded.

This exchange is totally sweet, and we can see where it's coming from. After all, the pic that Tom shared of his newborn son Jax — as Jax gave a huge smile and wave  was pretty much squeal-worthy.

We also imagine that Kristen is especially happy for Tom because this is his first child, after failing in the past to conceive due to a low sperm count.

"Because of my fertility issue, my sweet wife took a heck of a lot of hormones to make our son, but she still looks gorgeous!" he captioned the pic of his son. Awww!

Let's call it a tie: Both Kristen and Tom's kids are equally precious. Congrats to them both!
