T.I. recently celebrated his 37th birthday on Monday, and his reportedly estranged wife, Tiny, went above and beyond to show her love on his special day.

According to theJasmineBRAND.com, the Xscape singer bought her rapper husband a billboard in Atlanta which read, "Happy birthday Tip! From the one who loves & adores you the most! Mrs. H."

The grand birthday gift comes on the heels of news that the pair are working on their marriage, despite Tiny's recent claims that she is still moving forward with their reported divorce.

A source told the site, "They've been together for years and they truly love each other. Both of them realize what they have isn't worth throwing away."

The couple reportedly is trying to keep their rekindled romance away from the public for now, with the insider adding, "Everyone was in their business when they announced their split so they're trying to keep their marriage more private."

The two are reportedly back under the same roof again, with Tiny reportedly having the house she staying in on her own "occupied by someone else."
