Palin is already mom to 8-year-old son Tripp, whom she shares with her ex-fiance Levi Johnston, and 1-year-old daughter Sailor Grace, whom she shares with husband Dakota Meyer. The couple announced in December that they were expecting their second child together. Though they briefly called off their wedding before finally tying the knot, Palin and Meyer seem to be doing well, each having posted a sweet Valentine’s Day message to the other earlier this week.

“2 years ago today, this handsome man took me on our 1st date!! It’s been rainbows and butterfly kisses ever since,” Palin wrote alongside a photo of her and her husband. “Just playinn!! We have seen some of the highest highs – and lowest lows, but I am so thankful for where God has brought us, you are the greatest husband, father, and best friend that I could’ve ever dreamt of. Thank you for all you do and sacrifice for our family, you are my world!!”

Meyer echoed her words of endearment, sharing his own picture and saying, “You’re my world and I appreciate you more than anything. I appreciate all that you have given me in life. Happy Valentines Day.”
