Kim Kardashian West loves Kanye West to ''infinity''.

The 'Keeping Up With The Kardashians' star took to social media to share a sweet picture of her and her husband, where she gushed about how much she loved him.

She wrote on Instagram: ''I love you to infinity! Happy Valentine's Day!!! (sic)''

Kim and Kanye have had a great year so far, having welcomed their youngest child Chicago into the world via a surrogate last month. However, Kim has been keen to get straight back to work and doesn't want to take hardly any time off despite everyone telling her to ''slow down''.

A source said recently: ''Kim is determined to show the public she can have it all - she can be a mum of three, do sexy shoots, work all the time and still work out. She's doing all of these photo shoots so she can look like a super-mom. Beyonce hardly took time off work after having the twins and was looking sexier than ever in shoots right away, and Kim wants to do the same. Everyone's telling her to slow down, especially as Kanye is away in Berlin, and she has nothing to prove. After all, every new mum takes time off. But Kim's determined to do it all.''

Kim had previously taken to her official app to thank the surrogate who carried her baby.

She shared: ''I'm so grateful for modern technology and that this is even possible. It's not for everyone, but I absolutely love my gestational carrierand this was the best experience I've ever had. Our gestational carrier gave us the greatest gift one could give.

''The connection with our baby came instantly and it's as if she was with us the whole time. Having a gestational carrier was so special for us and she made our dreams of expanding our family come true. We are so excited to finally welcome home our baby girl.''
